For 4.07 Thatcher is going to to be in the ep. but i'm guessing right at the end like a set up for 4.08...

So basically let's talk about why we think Thatcher is coming back and problems it might have for the relationships of the show... Mer/Der Lexie/ Mer and whoever else!

Well.... maybe he's yelling on her for "steeling" Lexi? Or maybe he's come to his senses or I don't know :)

And Yes I like your new sig :)

Thanks! And I don't know if he is coming to his senses but maybe the Lexie thing!
