Apparently, Dr. Alex Karev has been around the block.. and back. Ausiello gives us some spoilers on what, or rather who, Alex has done in the past!
Question: Anything good coming up for Alex on Grey’s Anatomy? —Jesse
Ausiello: I don’t know if Izzie would consider this good, but the Feb. 18 episode will answer this burning question: Which of Seattle Grace’s other female docs has Alex hooked up with in the past?
Sounds like we'll just have to tune in for the February 18 episode to find out who the mystery woman is!
