Pitch (to Jack): What goes together better than cold and dark?
Rise of the Guardians an animated movie released in 2012, has many ( but subtle) homosexual implications. Actually, for a cast where there aren't many females in (Tooth being the only one main female character, along with Sophie, Cupcake and Pippa who are only children) a lot of Hoyay innuendos could be expected, especially between Jack Frost (who is a Launcher of a Thousand Ships in the movie) and Bunnymund, or Foe Yay/Hoyay things between Jack Frost and Pitch Black (these two pairings are usually the most popular ones in the fanbase).
Jack and Bunnymund have the most of Ho Yay things between them throughout the movie. Of course between a human and an anthropological rabbit, could you expect anything else? It is even shown as the Fan-Preferred Couple in the movie for a huge part of the fanbase (when it isn't Jack x Toothiana or Jack x Pitch).
Bunnymund throughout the entire movie, acts mostly like a type A Tsundere toward Jack, even if his "dere" side is only shown toward the second half of the movie, once Jack gained his respect, which looks like a Defrosting Ice King development.
That's interesting to notice that even if Bunnymund mostly acts like a jerk toward Jack, he is ready to do anything to defend him. That leads to a lot of Hypocritical Heartwarming moments in the movie. The best trope is during Pitch's first appearance at Tooth's palace.
Pitch (to Jack): Oh, good; a neutral party. Then, I'm going to ignore you. But, you must be used to that, by now...
Bunnymund: (jumps to attack him) Pitch, you shadow sneaking rat-bag, come here!
This moment sounds like a Big Brother Instinct moment, or possibly like a Rescue Romance. After all, that's there the first time where Bunnymund is shown nice toward Jack.
Later, there is a similar thing happening after Jack and the others went after Pitch and the Nightmares. When Jack fell from the sledge, Bunnymund immediately rushed to check if he was alright.
When Sophie came to the Warrens and found the Guardians, there is a moment where Jack and Bunnymund sat down and have a chat. During all the talk, Bunnymund is holding Sophie in his arms, and before Tooth and others come, these three definitely look like a family, with Jack and Bunnymund being the parents.
And later, when Pitch tried to make the Guardians thinking that Jack betrayed them by giving him his memories, there is the moment where Bunnymund is very devastated and yells at Jack that they should never have trusted him. Jack is very heartbroken by this.
And right before Bunnymund turns into a small rabbit they have a Held Gaze moment...platonic or not?
At one moment, Jack seems "flirting" with Bunnymund by sending him a snowflake which melt on Bunnymund's nose. Bunnymund smiles at him afterward. Aww.
Not to mention Bunnymund's reaction the moment where Pitch tries to strike Jack with his scythe by behind, he immediately tries to block it with his boomerang.
Their bromance is also very obvious. Don't forget the moment where Jack tries to make amend by trying to make the others children believing in Bunnymund after that this latter became a very small rabbit.
Bunnymund: He made you believe in me?
Jack and Pitch definitely. After all, they are so alike, which gives some good Foe Yay things between them. The two are very lonely, and just wish to be believed in.
Many moments in the movie are sounding like Pitch having a Villainous Crush on Jack. There is the moment where Jack is brought in Pitch's lair because he heard a familiar voice. There are a lot of parts where Pitch seems to flirt with Jack in his twisted way. There is even the part where Pitch corners Jack against a wall and comes rather close to him.
That doesn't help when Pitch is described as "seductive" in the artbook. And he never had been seductive toward anyone else other than Jack.
Don't forget the moment where Pitch and Jack first fought against each other. After that Jack used his power against him.
Pitch (laughing): Finally, someone who knows how to have a little fun!
Antarctica scene is the part where mostly of innuendos between the two of them are shown. This scene could imply that Pitch has feelings for Jack, once he saw Jack as a kindred spirit and a potential ally.
Pitch: I thought this might happens. They never really believed in you. I just tried to show you that. But I understand.
Jack: You don't understand anything!
Pitch: "No? I don't know what it's like to be cast out? To not be believed in! To long for... a family... All those years in the shadows, I thought no one else knows what this feels like... but now I see I was wrong."
In the script and Word of God said that Pitch was sincere in this part, and made himself vulnerable for Jack. That's probably one of rare times where a villain is sincere toward the hero and doesn't try to trick him. During all the story, Pitch's goal wasn't only to spread fear and ruling the world, but being believed in and accepted by others spirits, and possibly loved. This part hinted that he wanted to have Jack as a family, and being loved by him. The world family could imply many things: son, brother, and maybe lover.
Loving him as a son could be possible viewing his backstory, and in the books, once he became Pitch, he wants to turn every children into his Fearlings, as well as the main two protagonists of the books who are Nightlight and Katherine, as his Darkling Prince and princess because he wants his own child back. However, in the movie, Pitch doesn't seem to express this particular desire and only being believed in. His relationship with Jack could have been like brothers too, seeing the artbook. However, there is the sequel of this dialogue when Pitch made his We Can Rule Together speech:
Pitch: We don't have to be alone, Jack. I believe in you. And I know children will too.
Jack: In me?
Pitch: Yes, Jack! Look at what we can do! (shows him a sculpture made of ice and black sand) What goes together better than cold and dark?
This dialogue sounds like Pitch downright is shipping himself with Jack. Furthermore, the sculpture made of black sand and ice could mean anything. That doesn't help when you know that Pitch had been alone for many centuries, much longer than Jack. The OST about this part is even called Seduction.
The artbook goes further. One of first designs for Pitch showed him as a magnificient shadow who actually caressed Jack to persuade him to join his side.
And right after this scene when Jack refuses his offer, Pitch has a If I Can't Have You reaction toward Jack. Especially after that Jack gave his staff in exchange of Baby Tooth (that Pitch held in hostage)
Jack: Now give her.
Pitch: No. You said you wanted to be alone. So be alone.
According to the DVD commentary, Pitch was genuinely hurt by his rejection as he didn't want to be alone. Then, after this exchange between these two, Pitch reacted a lot nastier toward the Guardians afterward. That is shown in the final battle when Pitch tends to make a last strike, and attacked Jack by behind. His look seemed to be a real face of anger toward him.
You may think that Jack doesn't care about Pitch, but he definitely sympathizes with him more than the others. That's enough to see his face everytime Pitch mentions he isn't believed in, and he is probably the one who truly horrified when Pitch was defeated and was dragged back at his lair by his own nightmares
A lot of fans think that Jack would be the one to make Pitch change, as they think that Love Redeems.
Jack and Sandy, anyone? Unlike the others guardians, Sandy was definitely the only one who was supportive toward Jack. It's implied that the two were friends before the events of the movie. And when Sandy died Jack was completely devastated by this, and was overjoyed when he came back.
Pitch and Sandy too. Why did Pitch steal his ability? The movie hints that these two have a story behind their rivalry and not only because they are polar opposite. Then, during one scene, Pitch made a little scultpure of sand representing Sandy...before crushing it in his fists.
Without mentionning that Pitch is afraid of nobody...except Sandy. And Pitch loves fear too.
At one point, when they met each other for the second time, Sandy whipped Pitch many times.
