Really liked this movie, but was confused

Really enjoyed this movie, and was pleased to find Marcia Haydée playing the ballet teacher, with the character sharing her last name. I wanted to believe that somehow Angel survived, and joined Victoria and Vergara Grey, but it didn't look likely. Then again, what was the deal, with the prisoner/hitman sent by the warden, taking part in the theater heist, keeping the theater's guard subdued during Victoria's performance? I kind of thought he'd somehow joined forces with Angel and Nico, defying the warden, but then he went and killed Angel, who didn't appear to be aware of the part he had played at the theater, and greeted him (just before being killed by him) as if he'd not seen him since prison. If anyone happens to see this, and understood all that, I'd love an explanation. Anyway, it's a weird little movie, but I liked it.





Just make a movie that makes me care, one way or another. I'm open.
