Everytime I watch the first crossover between Grey’s Anatomy and Private Practice, I’ll always side with Addison. If Derek just listened to Addison in the first place then there’s a chance that Jen would have survived. Sure there was a risk for the baby, but Addison knew what she was doing. Delivering babies and looking out for the mothers was her area of expertise NOT Derek’s. Addison was the only one who had comman sense in that crossover, along with Alex.
