A Character from Frozen is in the Big Hero 6 Trailer

The first trailer for Big Hero 6 dropped this week, and the animated film from Disney and Marvel looks like a lot of fun. We see the main character, Hiro Hamada, and his robot Baymax trying to file a report in a police station. The corkboard by the police officer's desk features some wanted posters, and one eagle-eyed Tumblr user spotted a familar face: Prince Hans from Frozen. The jerk was sent back to his home by Queen Elsa, but it looks like he may have escaped custody.

Do you think it's just a fun reference, or does it mean the worlds of Frozen and Big Hero 6 are connected? What did Hans do to become a known criminal in San Fransokyo? Or is it a more evil twin brother? He does have a lot of siblings...

What are your theories?
