he was in Uliana's lair with Maleficent (aka his girlfriend that hes unhappy with), Hook, Morgie, and of course Uliana herself. They were planning princess Bridget's demise because she turned Uliana into a flamingo, on accident, but they dont care. After they planned to turn her into an ogre at the dance, they all needed some new outfits.
