Here's an interesting little Grey's Anatomy tidbit from last week. According to EW, we’ll find out in an upcoming episode that a major character - one of the original "Fab Five" - has a bit of a troubled background. In fact, he/she grew up in foster care.

It's got to be Alex, right? We know he has a big story line coming with the casting of his brother. Could it be he was in and out of foster care as a result of his troubled family?
