Pie and Beans
Look for me on the local news, I'll be the guy arrested for trying to burn down a Nintendo exec's house.
So like, the company (Tentsu?) that Mia works for who is responsible for the necrotoxin is a shell for New Umbrella, right? Which means she's an Umbrella agent. At least this is what I began to assume when I played through the ship.
I think there are just a lot of Umbrella-like nasty corps out there post the big bad Umbrella getting dismantled/decimated and Wesker dying. I mean hell, RE6 has us believing a cloned Ada could set up a new Umbrella no problem. Not everyone was as attached to the name.
It just remains to be seen if that is Chris at the end, if thats a new 'good' Umbrella or the same ol' evil one back to fuck shit up all over again.
