What's the latest with Arizona and Callie? Are we going to see them becoming more, um, intimate this season? Is the fact that we haven't yet a sign of trouble?

Here's TV Guide's take on that subject in its spoiler Q&A this week ...

Q: Are Callie and Arizona going to make it on Grey's Anatomy this season? They are great, butdon't seem as intimate as Callie was with Dr. Hahn (Brooke Smith).

A: Just because we haven't seen Callzona's sexy time on-screen, there's no reason to believe the ladies have intimacy issues. "I'm sure they've done it. I mean, come on!" Sara Ramirez said.

Seattle Grace's gorgeous lesbian couple at Izzie's May wedding.

Ramirez does, however, see potential speed bumps ahead. "They will deal with some very universal relationship-type issues," she says. "I'm kind of nervous for Callie."

"She's never been this happy for so long. Something's going to happen."
