Minor Spoilers on 'Private Practice' Season 4 Finale

Shonda Rhimes promises that the show will have a relatively quiet season 4 finale, meaning no crazy women cutting babies out of bellies.

Nevertheless, look out for a shocker in the last two minutes, Ausiello shared the spoilers. Does this have anything to do with Audra McDonald's impending exit? Rimes insists:

"It does not. She's been through a lot of hard times and I wanted a happy ending for her character so she's going to get it."

Does it have to do with an impending arrival then?
