What do you think...Who is the other Blackwell child?

i think faye because her mother liked a bit blackwell(episode9)

I think it might be Diana, because I was watching an interview of Shelley Hennig and she said "Diana's a good witch....for now." so I have a feeling that it might be Diana, also with the fact that she knew about dark magic and her book of shadows has a lot about dark magic in it!

I think most people would say Feye because of the way she acts all the time. However I think it would be more of a twist if we found it was somehow Diana. But wouldn't that mean that Diana's father really isn't her father? Interesting

i thinks its faye

I think it's Faye because in the episode Balcoin we find out that Faye's mother Dawn liked Blackwell

FAYE!

I figured Faye because when Isaac (Witch Hunter dude) said their was another Blackwell child I immediatly thought of Faye because they totally have the sister fighting thing going on but since this is the CW I'm expecting a twist and plus Faye is an obvious choice and it seems unlikely that the writers would go with a hunch everyone is expecting so I'm also thinking Diana but again it might be something we were never expecting, I'm just hoping its not Jake or Adam.

I think its Faye Chamberlain.

faye or Melissa would be cool

Jake or it could be lee labeque though I think it might be Lee Labeque, because he somehow Casted a spell or something with Faye in Ice and Fire! So that's what I think of it.
