The Wisteria Lane Welcome Wagon has moved way beyond a greeting and a coffee cake. In fact, for Desperate Housewife Teri Hatcher, her first scene with new cast member Nathan Fillion proved to be an unusually warm introduction.

"Often you'll hear actors say that there's the oddity of meeting someone and the next thing you know you're doing a kissing scene. Ours was, 'Hi, nice to meet you. My feet are going to be up in stirrups and you need to stick your head [between my legs]. Welcome to Desperate Housewives,' Hatcher told TV Guide at the ABC All-Star Party July 26 in Beverly Hills.

Fillion, who joins the cast as a dashing young gynecologist, will be moving into Mike's house with Dana Delany, who plays his wife, and according to James Denton, there is something dark and twisty about the new neighbors. "Something really dark happened in that house and that's why they have to move back. We don't know what it is, but I can't wait to find out."

For Denton, the first episodes of the new season will show Mike moving in with Susan and Julie and dealing with the challenges of parenting a teenager. "I try to be involved and [Julie] of course is like, 'Who do you think you are? My mom and I are best friends.' There is a lot of comedy that can be mined from it." - Reporting by Carita Rizzo
