Watched Big Hero 6 tonight, been meaning to for a while, got a good reason finally. First of all, that was a REALLY good movie. I think I enjoyed that more than the last 8-10 movies I've seen. Also, I went in thinking "What would work as a connecting point to Kingdom Hearts besides what was mentioned?" Well...Wall of Spoilers!
The sacrifice Baymax made, using his armor to save his friend from being trapped in another dimension but dooming himself to be instead. That sounds pretty much exactly what Aqua did for Terra at the end of BBS. Why do I now feel like what Sora does in San Fransokyo (or maybe even his reason for getting involved, what if he finds out about the portals!?) is going to result in finding how to or actually rescuing Aqua & Ansem?
