As Grey's Anatomy Season 8 moves towards its end, the residents get ever closer to finding out their fate as doctors.
Season 8, Episode 21 is titled "Moment of Truth," and that alone should give you a good sense of what it's about. According to Spoiler TV, this is the episode where "the residents travel to San Francisco for the oral board." Moment of truth indeed!
Meanwhile, "sparks fly" once again "when Richard [James Pickens Jr.] and Catherine (Debbie Allen) bump into each other at a hotel" — more Debbie Allen, yay! — and "Alex Karev [Justin Chambers] feels guilty about being away from the hospital when Tommy's health takes a turn for the worse." Will that guilt interfere with his boards performance?
