Shang was angry at Mulan after The Reveal not because of honor, but because he is gay."Ping" just saved his life. There had to be something going on besides "honor" that would make him so pissy about Ping turning out to be a girl. They had a few good moments before then, and it's not unreasonable to speculate that he began to respect Ping for "his" accomplishments during training (not to mention Ping's supposedly good looks). So Ping turning out to be a girl broke his heart. He was unable to think rationally for some time after that, explaining his strange behavior afterwards. At the end he finally got over his heartbreak over "Ping" and accepted Mulan's true identity.
Mulan is FtM transgender.She's kind of excited/jittery with anticipation about going before the Matchmaker, but she doesn't seem at all happy dressed that way. Throughout the whole song "Honor To Us All", she doesn't seem to be really enjoying the make-over or dress-up she's being put through. Only until her family seems so proud of her does she finally seem to not mind it. When she goes into the army as a man, and with being a man in ancient China she finally has this sort of freedom to express who she really is. , It doesn't even drastically change her song "Reflection." It just fits even more so.
One of Mulan's ancestors was a traveler from EuropeYou ever notice how one of her ancestors doesn't look remotely Asian? It's possible they have European blood and thus European features. There are Romans who got captured at Carrhae (53 BC) and force-marched east - some say until they reached the outskirts of the Chinese empire. Then there's the Tocharians, a "white" European people, that settled in what is now Xinjiang in ancient times, and even today the Uyghurs of Xinjiang often have European features.
The Great Stone Dragon was helping Mulan all along.Right before she decides to go to the army, Mulan is seen sitting right at the foot of the statue of the Great Stone Dragon in the rain. It noticed her plight and plan, and being the greatest and most powerful of the guardians, decided to help her without anyone needing to awaken it first. So, the Great Stone Dragon followed Mulan in spirit form (or more fantastically, it somehow imbued her with its essence), which is why Mulan never died or was discovered before she had earned enough good favor with Shang to dodge execution, and why she was able to escape Shan Yu twice. This also explains why the statue of it crumbled so easily - with the guardian itself gone, that statue was just a useless hunk of rock waiting to fall.
Mushu and the Great Stone Dragon are really the same guardian.Mushu was once the mighty Great Stone Dragon, but as penance for screwing up, the ancestors not only stripped him of his guardian status, but drained his spirit of its powers, rendering him a small dragon with almost no combat prowess, and erasing his memories as well. They intended to send him after Mulan from the beginning, as a chance at redemption for him, but they didn't want to remind him of his past before he earned his place again by proving he could be a good guardian without all the powers of the Great Stone Dragon. To this end, they sent him out to "awaken" a fake statue of himself, knowing that it wouldn't work and Mushu would take after Mulan himself. However, some of them were secretly hoping that he would fail or get himself killed, and were still hesitant to allow him to be a guardian again, hence the grudging expression on the ancestor's face when he restores Mushu to his position as a guardian. This also explains why nobody seemed to give the fact that Mushu destroyed the statue of the Great Stone Dragon any importance.
The message Mushu gave the emperor's adviser was not a fabrication.Given the initial strategies of General Li and that they ended up near the pass to Beijing, and that Cri-kee's initial draft for Mushu, it's possible the letter was true, just not sent by the general. The letter might have even gone like this: "My son, we're guarding the pass, but our scouts report that the Hun army is vastly more powerful than us. We need you to bring whatever men you can to the pass with cannons, so that we will have the capacity to defeat them, and come immediately." So though the letter was false, the words were in a sense true, and through the lie, Mushu helped save China. (His accident with the rocket later though would be better to not have happened.)
If things with the Matchmaker had gone well at the beginning of the film, Mulan would have ended up married to Shang anywayAlthough granted, Shang would probably have been dead due to the Huns, but we'll ignore that for a moment. Mulan's father is obviously a war hero, and probably one of pretty great renown considering General Li and Chi-Fu both knew who he was. ("The Fa Zhou?" "I didn't know Fa Zhou had a son!") For such a great hero, who only has a single daughter, the matchmaker could only consider a family of somewhat equal standing. Who better than the son of a current general?
If Mulan hadn't been discovered as a man, she would have ended up married to Shang anywayRelated to the above. She might've gone home, passed her matchmaker test fairly this time with her newly earned discipline and is betrothed to Shang. Shang begins to think his new bride looks awfully familiar...
Mulan and Shang will name their first child "Ping".No guesses why.
San Yu is the Emperor's Bastard.Think about it. When he is first mentioned, what's the situation? Chi Fu exclaimed, "No one can get past The Great Wall!", and when his name is mentioned, it's as if that alone explains how. Add to that the emperor suddenly deciding shit just got real, and you have the seeds of the theory. Now, add in Shan Yu's obsession with proving himself, not to the Chinese people, not to the Huns... he wants the Emperor to acknowledge him. He calls him old man. Regular Chinese soldiers recognize him on sight. Clearly the Emperor's bastard wanted to be acknowledged, and when he was denied, he threw a hissy fit in the form of blatant treason and joined the Huns to help them wage war on his father, ala Mordred.
Mushu will be tight with Shang's ancestors.Mostly because Mulan's ancestors tend to be jerkasses towards Mushu. As the ending of Mulan II would indicate, they won't like Shang's ancestors and they'll likely be annoyed by Mushu's friendship with them.
Shang will have one ancestor in common with MulanThis will make things weird between Mulan's ancestors and Shang's ancestor, knowing that because of a fling that happened waaaaay back when, the two new lovers are related. By only a speck of blood from mllenia ago, so it's not realy incest.
The hawk is a Horcrux.How else would it have survived?
The falcon is Shan-yu's guardian.In a deleted scene from the movie,it showed Shan-yu having the power to look through his falcon's eyes. It could mean that the falcon is meant to watch over him.
There was more than one Guardian involved. Khan (the horse) was also a GuardianDefinitely smarter and braver than your average horse, and likely Mulan's father's old warhorse. The Guardians seem to be based on the creatures of the chinese zodiac (monkey and boar are shown). When Fa Zhou came home from the war with a bad limp, the Guardian that was supposed to have kept him safe from harm was punished by the ancestors and paid penance by staying in his mortal form. This explains why the horse was super intelligent, as well as being awfully sprightly for an ancient warhorse. It also explains why Mu Shu was a bit rude to him throughout the movie. There's more than one redemption story going on here.
Mulan and the little girl who lost her doll are the same person.
Chi Fu is a eunuch.It would explain why he's so effeminate, and why he's always so angry.
Mushu suffers from some form of agnosiaMushu is not trying to insult anybody when he calls Khan a cow; he truly does see Khan as a cow. He also rides a panda of all things when delivering his forged message. It was not because he couldn't find a better ride, given that there were other horses on the camp that he could blackmail into helping him; it was because he saw the panda as an actual horse. He manages to identify correctly the cricket because, the cricket told him he was a "lucky cricket" from the start. He might also see himself as a dragon because, for him, it is his Informed Species. Given that he was released from his duties as a guardian, it's possible that the agnosia is part of his punishment.
Mushu is the spirit of a smith's cooling stream.He belongs to the stream of one of those blacksmiths who use running water instead of a still trough in their forging. This caused him to breathe steam when he gained a corporeal form, and eventually fire, and made him hot-tempered like a tiger. This is why the ancestors don't accept him as a dragon- because to them, he isn't one, he's just a fire-breathing lizard-spirit who happened to come from a stream like a dragon.
Fa Li has suffered miscarriages.It seems odd that Mulan is an only child, plus an only daughter, in a society where women are pressured to bear sons. Also, both her parents look considerably older than her, I'd say 50 something while she's in her early 20's if that old. Possibly, Li had a lot of miscarriages or kids that got sick and died before she had Mulan. It's also quite likely that a young Mulan asked for a little brother (possibly too young to know how babies were made at the time) and her parents, rather than go through the heartbreak of another miscarriage, decided to get her a puppy instead. That would be the dog called Little Brother.
Mulan was born in the spring, late winter at least.In Chinese tradition, a baby isn't officially named until they are 100 days old. (If Fa Li did have miscarriages, she may have called her daughter "Not This One" in the meantime.) This gives parents plenty of time to think of a name. Mulan's parents may have looked at the blossoming magnolia tree in their yard and thought "Mulan" was a pretty name for a girl. (They call it the "mu lan tree" in the sequel. "Mu lan" means "wood orchid" in Chinese and is used for the magnolia.) When the movie begins, the tree is in blossom. Likely, Mulan's birthday was recent and her parents considered her just old enough to start thinking about marriage.
Mulan is the guardian Dragon- or at least carrying his spirit.When Mulan makes her decision to join the army, she is standing at the foot of the great stone dragon. When she was born the spirit of the guardian was reborn within her. Which is why Mushu couldn't wake him up- the spirit within the stone dragon was already gone. his lie, it's because they were boorish brats who wouldn't understand a man's love for his progeny (especially when said offspring is a female, in third-or-whateverth-century China).
Chi-Fu is the most badass character in the movie.Recall the "I'll Make A Man Out Of You" sequence, where Shang brings in the weights that are so heavy they more or less immobilize everyone who puts them on. Notice that Chi-Fu is carrying the box containing them, and it only mildly troubles him. Calling it now, Chi-Fu could have won the war by himself had he actually given a shit, and he only acts the way he does in the movie because he wants to know what this strange feeling called "cowardice" feels like.
