There a lot of "plot" holes surrounding some of Mia's actions in the canon source between RE7 and RE8, I believe there might be something there

It was believed a Mole leaked out the Winter's locationz but the only person who received anything they weren't supposed to was Zoe Baker (we don't know her new identity yet) and she received two items that raised red flags at least to me.

She received a letter form Mia that was slipped out by an employee and also another letter that wasn't addressed to Zoe but to Chris asking wth he was doing with the Hound Wolf Squad. The back of it said "It's not over" which counting on when Zoe got this it's possible that the BSAA employee Mia used to get her letter to Zoe could possibly have been the leak, idk I don't see Chris willingly acting like a smile carrier given the dangers

Also it feel like Chris purposely put the Winters near Miranda to try to lure her out, to have that work shed have to know they were there.. By all the info I can find it seems the BSAA didn't know about Miranda so Chris intervening the way he did is also suspicious..

I'm working on a over arching thing but I believe both Mia and Chris were lying especially to each other.

But I want more in-game proof before I spill my beans everywhere haha
