A young boy is desperate need of a transplant and the only organ donor around is also a serial killer. And Meredith meets McMommy!
Derek’s mom, Carolyn (guest star Tyne Daly), comes to town. This has Meredith a bit of a nervous wreck. Izzie tells her she should just try to put on a chipper face. But what exactly makes for a chipper Meredith? Apparently, it involves things like ponytails, forced smiles and not really talking much. Yeah, it’s as weird as it sounds.
Mer’s change-for-the-chipper doesn’t make the impression she was hoping for. Fortunately, she’s saved from a prolonged conversation with McMommy when she has to treat convicted murderer William Dunn. Who says there’s never a serial killer around when you need one?
