Jack Bass, devious uncle of Chuck Bass, is set to return to the show later this season, TV Guide reports, having spoken to actor Desmond Harrington.

"I will be back," says Harrington, who plays the character. "I think it's episode 15 or 16 where I show back up this year. It's fun playing Uncle Jack."

When we last saw Jack Bass, he tried to attack Lily van der Woodsen (Kelly Rutherford), who took over Bass Industries for one-time stepson Chuck.

Jack was then sent packing back to Australia with a sore jaw after being punched by Chuck. What do you think brings him back to New York City?

Harrington, who currently plays Det. Quinn on Dexter, says the producers if Gossip Girl asked him to come back, but he doesn't know the plot details.

However, the actor says he hopes to continue making Chuck's life a living hell again: "I think I am there to screw that kid's life up basically," he says.

"I think [Jack Bass] might be, out of all the most evil characters the show has ever had on it, the single most evil character. He's just pure evil."

We learned on the Season 2 finale that Jack slept with Blair, though this was practically an afterthought. Will it be explored more this season?

Are you excited to see the return of Jack Bass?
