"Derek, I need you." Those are four words we never thought we'd hear Dr. Addison Montgomery say ever again.
But, to get to that point, let's flash back to 14 hours earlier:
Naomi and Addison's brother Archer wake up in each other's arms. Archer begins to get a little randy—much to Naomi's pleasure!—but the good time quickly turns into a nightmare when Archer suddenly has a seizure. He shakes violently and falls to the floor.
Thinking quickly, Naomi dials 911. In the hospital ER, Archer sits up, claims he's perfectly fine, that it was just a random seizure. But then, he asks the impossible: Can Naomi keep the seizure secret from Addison? She has to tell her best friend, right? We would.
