E! Online has some interesting Private Practice spoilers for this week's and upcoming episodes today. Let's get down to the spoiler Q&A, shall we?

Q: Anything on the Private Practice side of the crossover?

A: It turns out Archer's tumor is a lot more serious than anyone imagined. It's not a tumor at all - he has parasites on the brain. Archer refuses treatment until he cannot make the decision for himself, which is when Addison, Archer and Naomi fly off to Seattle and the Grey's Anatomy universe.

Q: What's going on with Violet's baby?

A: Violet (Amy Brenneman) finally realizes she is pregnant this week when Dell lets her hear the heartbeat, but she has a panic attack. She is not ready to be a mother at all. The possible baby daddies will find out the news as well, and they're a little pissed she's left it up to Cooper to take care of her.

Q: What is with the abrupt ending to the hot storyline between Wyatt Lockheart and Addison on Private Practice?

A: Wyatt got another job! Or rather, Jay Harrington, who plays Wyatt, got another job. He's going to be appearing on a new ABC comedy called Better Off Ted. Archer (Grant Show) is his replacement, and Archer's tumor is motivation for Thursday's big Grey's Anatomy-Private Practice crossover.
