Following her fall out of a window, Blair still can't remember Tea's deep, dark secret, so she decides to seek professional help -- from Marty. Yes, she is that desperate. But the good Dr. Saybrooke is worth it, because Blair ends up remembering that Tea had Todd's child and never told him. Question is: Will she use this info? We know she wants Todd all for herself, with Tea out of the picture. Look for that operation to kick into full effect this week. One element of that plan: pretend she's sicker than she is to get Todd to care for her.
But Blair can't count on the feelings between Todd and Tea being dead. Because, well, they're not. Poor Tea, in addition to dealing with Blair, has to put up with the threat of Ross exposing her child -- since he thinks it's his.
Amidst all this, we finally get to see the mystery child -- and they have a connection to Llanview that has nothing to do with Todd, Tea, Ross, OR Blair.
