New Grey's Anatomy star Jesse Williams (Dr. Jackson Avery) has made quite an impression on fans this season already, and we have only begun to explore his character.

With his good looks and charm, it was really just a matter of time before the Mercy West transplant got some lovin’ on Grey's Anatomy. The only question is, who with?

Grey’s is getting a little crazy,” he told TV Guide Sunday. “I think there’s going to be a lot of changes for my character. Jackson Avery has a lot of big things happening.”

And yes, that means romance.

“There’s a lot of relationship changes. Within the group,” he teases. Asked if sparks fly between he and a fellow Mercy Wester or Seattle Grace original, he played it coy.

“Well, because it might be one of both,” says Williams. “Jackson ... he’s a man.”

Indeed. What he does give up is that a relationship with Sandra Oh's Cristina Yang, which was hinted at in a previous episode when he made a move, is not in the cards:

“I think Cristina is giving him a lot of flack, so you can only bang your head against a wall for so long ... I think he’ll wise up and try to get some attention elsewhere.”

We'll also get a glimpse of Jackson's background. On one of the upcoming Grey's Anatomy episodes this spring, the show will introduce Jackson’s ailing grandpa, Harper Avery.

Chelcie Ross, a.k.a. the guy who taunted Mad Men’s Don Draper as Connie Hilton, will play Harper, the namesake of the Avery Award bestowed on Meredith’s mom, Ellis.

This will help form a bond between Jackson and Meredith Grey - but does it play into some fans' theory that young Dr. Avery is a secret love child of Ellis and the Chief?

“It’s not relevant,” says executive producer Betsy Beers, and “not on anyone’s brain.”

Still, we look forward to seeing these events play out in the coming weeks.
