Jack Bass (Desmond Harrington) returns to Gossip Girl next week, and Chuck welcomes his uncle back to New York the best way he knows how. We're talking about women, booze and all-around crazy times.

In the sneak peek from "Con Heir" below, Chuck reveals that he just donated a new wing, in Jack's name, to the hospital where his life was saved, with a ribbon-cutting ceremony set for that night in his honor.

That event will quite possibly set the stage for various shenanigans (see the "Con Heir" Canadian promo), as always ... what's an episode of Gossip Girl without a high-society event bringing people together?

It's nice to see the Bass boys having fun, in any case. Check out the clip:
