I agree Birkin, and I seriously hope that old man to be Spencer, now it has almost been confirmed, and the place wesker and chris fight in is SPENCER'S ESTATE. omg, I'm not able to even imagine what wesker is gonna tell Spencer...EPIC MOMENT btw.
And the fact that wesker is there for spencer and not for chris makes sense now, I couldn't see wesker in africa for chris only. In code veronica he was there for the t-veronica virus, not chris. Same goes for re5, he's there for spencer, not chris. I love Capcom's way of acting!!
