According to Grey's Anatomy's Jesse Williams, the doctors at Seattle Grace are still licking their wounds after a crazed gunman attempted to kill Dr. Alex Karev (Justin Chambers) and Dr. Derek Shepherd (Patrick Dempsey) during May's two-hour season finale.

"We really deal with the trauma of it all, and everybody has to essentially try out again and prove that they're worthy, that we're all worthy of going back into surgery," Williams, 29, tells "We have to go back and put people's lives in our hands, literally."

Though Dr. Karev and Dr. Shepherd survived the shooting, Williams-- who will appear in What Holds the Future? at Colonial Williamsburg in Virginia Saturday -- says it'll take some time before things go back to normal.

"Everybody's kind of trying to get their feet back under them," he says. "I think that the shooting also brought several kind of groups of people closer together."


According to Williams -- spoiler alert! -- Dr. Cristina Yang (Sandra Oh) and Dr. Owen Hunt (Kevin McKidd) plan to say "I Do" this season.

"There's a wedding, and it's just kind of sudden for everybody," he tells Us. "But I think when people have gone through something really heavy, you kind of let everybody just be. You don't get too involved or question is short. Let's do what we want, when we want, and see what happens."

The seventh season of Grey's Anatomy premieres tonight at 9/8c on ABC.
