Time would tell just how nullified Jack was or not. It wouldn't be too big of a deal, he'd already had to live powerless before. He'd rather not, but he could buy just as well without his power if need be. It was just a shock, and a small bit of worry that he would get sick again.

His powers were still dull enough that he didn't feel Castiel, or anyone else, nearby. That would have made the empty, worrying feelings plaguing him easier. The snacks were always welcome, of course. One doesn't grow up around Dean and not love snacks.

When the seat across from him is taken, Jack looks up ready to greet whoever it is. Though, he blinks a second before a grin covers his face. "Cas!" He calls out excitedly. He hasn't had his soul back long, and while part of him is filled with misery for what he has done, the sheer sight of Castiel banishes all of that for now.

He's not alone.

"Uhh, I don't really know. But it is very good." He motions to the plate, a silent offer for Castiel to try one of the canoli-like desserts.
