It’s a morning for mourning as Izzie deals with the loss of Denny by lying motionless on the floor in a prom dress. Meredith is nominated to help her through the grieving process because she’s “dark and twisty” inside. George is actually the first to reach out, or in this case, lie down with Izzie. Nothing changes. Cristina also strikes out when she hits the floor with Iz. It’s gonna take some time.
Meredith confesses to Cristina that she slept with Derek at work and lost her panties. No worries. Addison finds them and decides to pin them to the bulletin board at work. Seattle Grace really should invest in a lost & found box. Addison is obviously a little ticked at Mer-Der. Infidelity will do that to a person.
