Why did Lexie board on that plane to Boise? I mean, I understand, Mark represents Plastics, Grey for General, Yang for Cardio, Arizona for Peds & Derek for Neuro...But why Lexie? Help!

I think she boarded because Shonda đã đưa ý kiến that they were going to kill her back at the hospital bởi doing something as simple as hitting her head. But then sh e đã đưa ý kiến she couldn't die without Mark bởi her side. So they had to put her on the plane. Plus, she's Lexiepedia. She is brilliant and for an extra set of hands
