While those last few seconds may be can't miss, the final moments of "Au Revoir" will leave fans wondering about Neal (Matt Bomer) and Peter's (DeKay) future.

"There were still directions to go, but I think the way they wrapped it up was really well done in the sense that they didn't try to tie everything up into a nice bow," Bomer told Hypable. "They really left some things open-ended and left a lot up to the viewer's imagination, which I always think is more potent than anything you could put down on a piece of paper."
