- Newt Scamander was expelled from Hogwarts, but Dumbledore still maintained contact with him and entrusts him with the task of fighting Grindelwald very much the same way he would trust Hagrid years later despite being forced to expell him from the school. Dumbledore, at the very least, appreciates Newt given the way he speaks about him to the Aurors.
- It's a testament to how much Jacob loves Queenie that he isn't angry or horrified when Newt removes the love potion that she used to drug him and drag him half-way around the world to marry him. His initial reaction is one of exasperation and annoyance and after he calms down, he has a heart-to-heart with Queenie that since their romance is illegal in MACUSA's eyes (and even if it's permitted in Europe, still subject to discrimination) and he isn't worth risking her freedom for.
- It seems like Jacob Kowalski has recovered some of his memories from his adventure with Newt and the Goldstein sisters, given his eagerness to go on a new adventure with Newt. In any case, it's heartwarming in itself to see them reunited.
- Doubling as Tear Jerker: in the San-Diego Comic Con Trailer, Dumbledore looks into the Mirror of Erised and sees himself living with Grindelwald.
- Newt and Tina are showing signs of being a Battle Couple in the third trailer.
- Newt continuing his duty of rescuing magical beasts, specifically by taming the Zouwu, breaking its chains and taking good care of it after the years of mistreatment it had to endure at the Circus Arcanus. It pays off later on as the beast proves very useful to fend off the Matagots and escape the French Ministry of Magic. And following that escape, the Zouwu essentially behaves like a Big, Friendly Dog with Newt, being happy with its new tamer.
- The reason why Dumbledore chose Newt to go after Grindelwald? Because Newt doesnt seek power.
- A behind the scenes picture reveals that Newt keeps a picture of Tina on the lid of his case. Unlike Leta's picture, which was hidden away, it's there every time he opens it.
- What's more, the picture is from a newspaper article talking about her reinstatement as an Auror.
- In the film, Newt learns that Tina was led to believe that he was set to marry Leta instead of his brother. Thus, for most of the film, there's clearly some tension between the two because of this misunderstanding. But during the scene where they sneak into the French Ministry of Magic, Newt finally tells her the truth, resulting in an incredibly sweet moment where the two's budding romance is revived. Tina even references the same 'Salamander' line that Jacob told Newt not to bring up... because she recognizes the comparison he was trying to make about her eyes. Because she read his book from cover to cover.Newt: I got this picture of you from the paper, but it's interesting because of your eyes in newsprint. See, in reality they have this effect in them, Tina. It's like fire in water, in dark water. I've only ever seen that... I've only ever seen that in...
- Dumbledore does his best to comfort a crying Leta, and in general is the lovable Team Dad we all know and hold dear to her.
- Early in the film, Newt tells Leta that his brother, Theseus, is a huggy type. The two brothers indeed hug with the intention of Theseus telling Newt that the Ministry is watching and following him. Later towards the end of the film, Newt initiates the hug towards Theseus this time, with both feeling the loss of Leta. He also affirms his brother, saying that he now has a side.
- In a villainous way, Grindelwald handing Credence a new wand at the end. The latter only had his Obscurius awaken all because he tried to suppress his magic. Now, there is a sense of hope in this moment, as he is essentially being allowed to train and use magic properly, even if it's for the bad guys.
- While also a moment of funny, it's heartwarming to see Professor McGonagall put the mouth disappearing spell again on the female student who was talking bad about Leta. This shows that while she does take offense at what Leta did to the other students, she also cares for them (including Leta) and doesn't take any crap when the students shows otherwise.
- Newt and Theseus get steadily closer to each other over the course of the film. This culminates when Grindelwald threatens to kill Newt at the mausoleum and Theseus noticeably moves to stand beside his brother. The two of them fight side-by-side for the rest of the battle and later, on the Hogwarts bridge, they stand close together while waiting for Dumbledore. Whatever their sibling rivalry may have been in the past, they are now presenting a united front to the world. Also ties into a Tearjerker, as this contrasts poor Tina, who has seemingly lost her sister Queenie to Grindelwald.
- Yusuf Kama's reaction when he meets his younger half-sister Leta, born from the man who abducted, roofied and raped his mother? He tells her she's beautiful.
- When Travers and his band of Aurors arrive at Hogwarts to confront Dumbledore about Newt's appearance in Paris, one of the students marches right up to him and defiantly tells him that Dumbledore is the best teacher the school has.
- Leta's brother being dead is supposed to be a secret - or, at least, that she killed him - is supposed to be a secret. Dumbledore knows it, but Newt interrupts before Dumbledore can mention it, implying that he already knows and that Leta trusted him enough to tell him.
