One thing that Bioware does really well is make you feel like your character really has developed a bond with their squad throughout the course of the game. It’s honestly a huge reason why I enjoy their games so much. It’s why people have such an attachment to them. What would a Bioware game be without your bros?
Regarding the ring exchange scene, apparently some leaked storyboard showed an internal monologue of Victor's. He was sad Yuuri didn't come out and say it was an engagement ring. "So this is what he means." The Japanese fanbase picked it up. Which is why he looks a tiny bit sad. I wish they hadn't cut that part, but at least Victor understands Yuuri's real intentions. Thus the "we'll get married after winning gold," comment. :') But it would have been nice with Vic's original thought. Oh well.
