Actually, I never thought about Maya being A, but now that あなた mentioned it, it could be. I don't know what happened to Melissa either, she hasn't been in a lot of episodes recently.
I don't thinkk Maya is A - I don't think that anybody who has been involved in A's cruel jokes (Maya suffered with Emily) like that would be involved. Maybe the actress for Melissa is ill, または something? I've been wondering what happened, too...
i don't think Maya is A. She was thrown to somewhere and that was bec. of A. Torrey DeVitto (Melissa Hastings) just got married. Maybe she is really pregnant in real life...or she maybe on a honeymoon vacation with his husband Paul Wesley.
