"Remember we used to like working on Greys?"

Katherine Heigl and T.R. Knight are finally leaving Grey's Anatomy! They're both leaving because they're divas to pursue "bigger things." ABC hasn't confirmed their departures yet, but that's on it's way. What will Grey's do without George or Izzie???

You know, there once was a time that I felt bad for T.R. and what he went through with Isaiah, but after hearing that he's become just as big as a diva as Katherine, I'm over him. Who knows what will happen with Greys. I'm sure it'll survive, but will it ever get back to being good again??
