Kim Raver's Dr. Teddy Altman hasn't been on the show much over a year, but soon enough, Seattle Grace's current Cardiac God will be the center of a major love triangle.

When James Tupper resurfaces as Dr. Andrew Perkins, the crisis counselor who helped the staff recover from the hospital shooting, that opens up a whole host of issues.

“He’s a bit nomadic - he’s traveling - and he’s back in town when he contacts her,” Tupper says, adding that Perkins immediately tries to reconnect with Teddy (Kim Raver).

Before long, they’re picking things up where they left off at the end of Tupper’s first run: “They liked each other before, so they’re trying it again,” he tells TV Line.

There's only one slight problem. She's married to Henry (Scott Foley).

Naturally, Andrew will be kept in the dark about that detail for now.

“Yeah, she hasn’t told me about that,” Tupper said, noting that things will progress to the point that, by season's end, Andrew will drop a big question in her lap.

“I do make her a proposal,” he says, although he won't elaborate with, say, her answer. “I’m waiting to see just like you are, but I think there’s a chemistry there.”

How will Henry react? Who do you think is a better match for Teddy? Discuss.
