I'm just going to point out a few things.
Charlotte said she spoke to her social worker today even though either Donna or Charlotte commented that she doesn't have one anymore...
Also she met with Ashley n kept the correct distance but magically out of nowhere the correct distance wasn't kept n both of their lippy lips locky locked.
My personal opinion Charlotte met with him with intention of something happening to hurt tia because if you hate the yout so much, why are you meeting him? I also think she does the lives just to see our responses afterwards
