Ok, so... Lexie Grey.... If Lexie tries to catch Der, he won't take her, becuase A) She's Mer's half-sister, and B) He loves Mer and won't get over her that fast.?? And on that note, mer can' t leave der, right? Ughhh i need major spoilers to ease my worries. I hope Mark or Alex will want Lexie, cuz i LOVE MER/DER! ok this is long, but any opinions??
