SO Cristina is still cardio. Alex is definitely in peds surg. Lexie? I don't know. She was into plastics for a bit but that was perhaps she was dating Mark? Well as a 4th year, she might start de facto specializing like everyone else. Jackson's doing plastics. Although April stated neuro was her focus, I see her going more and more into trauma. Now, Mer was definitely headed toward the neuro route, but as of the promos for 8x06, she's in pink scrubs? So OBGYN? Can't be peds surg since she'd still wear the powder blue scrubs. Maybe neonatal? But she'd have to do peds surg first... I'm thinking OBGYN as the OBGYN residents that were on the show (remember the "I don't know" doctor treating Sloane's baby) wear pink scrubs.
