About 'dat
(SPOILER)
Most of the hints are in the love duet/ villain song
Anna: Okay, can I just, say something crazy?
Hans: I love crazy!
- One of Hans' verses subtly reveals his true intentions... "I've been searching my whole life to find my own place." As he sings this line, he gestures to Arendelle. This is a demonstration of Hans, in a sense, claiming the kingdom of Arendelle as "his place." According to Kristen Anderson-Lopez and Robert Lopez, the song's lyrics were created in such a way purposely, as it's meant to stand as Hans' official villain musical number, though disguised as a love song to keep his villainous intentions a secret until the third act of the film. However, once the truth was revealed, the song's dark side was meant to be more apparent.
- This song also introduces the audience to the constant use of doors as a metaphor in the film. This doubles as a villain song, for it is later revealed that Hans' love for Anna was not real love, and that he was only using her as a tool to marry into the throne.
- One line between Anna and Hans hints at Hans' deception..."our mental synchronization can have but one explanation." While singing these lines, Hans and Anna dance robotically. In a sense, Hans is behaving like a machine. His emotions and his feelings are not real, he is merely manipulating Anna into making her love him so he can marry her and become Arendelle's king. During this entire scene, Hans doesn't feel anything. He is essentially an automaton, a heartless robot.
- Also when attacking Elsa's Ice Castle, Hans looks up at the Chandler and aims the Crossbow at a attempt to kill Elsa and make it look like a tragic accident and him a hero
- And when he's told that Anna is in danger, he looks way too happy, like he smiles and almost breaks his character, because he's too excite of the idea that he good look even more of a hero and thus be stepping to the throne.
I knew about Hans being evil since about September maybe even earlier when the kids books were leaked, but I've seen the movie 3 times and during Hans's plot-twist everybody in the audiences gasps in shock; so imo the twist isn't too predictable though a rare few may pick it up if they're paying attention, mostly during the villain song.
