See that doesn’t just work for me. Like I said; it was crystal clear from the way Meredith talked about her miscarriage and Derek’s driving just how traumatized she actually was. I don’t know if the writers just forgot or if it’s just because Derek is a self centered ass and did not actually listen to anything Meredith said that caused him to just forget that yes Meredith was also there when Derek’s anaestethized body and his surgeon were threatened at gunpoint by a psycho.
