"The pager is sacred. Sacred sparkle." -- Izzie

A sparkly pager, some quick-drying cement, and a field of candles all play into tonight's 2-hour episode -- the Season Four finale of Grey's Anatomy. Has it really been only four seasons? Because it seems like so much more.

Anyway, tonight we learn a little more about some of the interns' history. For one thing, via a therapy session (and why can't I have Amy Madigan as my therapist?), we learn that young Meredith saw her mom slit her wrists, then had to wait for her to pass out before calling 911.

Meredith says her mom wanted to die, but by the end of the episode, she figures out that she really didn't want to die. Being a brilliant surgeon, her mom would have known the faster road to death entailed slitting her carotid artery.
