accidentally find the possible answer.

You pull Charlotte out of Anna fully by her mouth. But as you pull, you notice that you grip something more than a loose skin of Charlotte. Feels like it's.... another skin inside Charlotte.

Huh, makes more sense now..... I guess....

Once Charlotte is laid down beside Anna you open her mouth and try to grab the skin of the one how hijacked Charlotte. After couple of seconds, you manage to get a hold of something other than Charlotte's inner body. You pull forcefully, eager to know who was the imposter.

From beneath Charlotte's soft lips, emerged the face of.... Governor?!

The hell is going on here?!?!?
