If Garth'zel's arms were free, they would have windmilled to help him stay upright, but as they aren't, he just staggers instead as he draws on the Force to help with not falling over.

After he's sure he wasn't going to either fall or drop anything, he speaks up. "He does, huh?"

Sounds like he's got his answer regarding if Ezra was staying behind on Lothal or leaving with him, considering the kid hasn't wanted hugs before now.
