Knowing Annalise, she was probably faking that pregnancy as a means to get close to Wes' mother. I don't trust that bitch
I think she legitimately had a child by Sam but lost it somehow and she was involved or knew about who was involved in Wes' mother's murder. I also think Christoph is his real name and Wes is his mother's name.
Pretty weird episode am I the only one that felt that theres was a lot going on.. when I was finally processing something they hit me with something else
