Yes, Grumpy was out on the wall of the castle when the curse came and Doc helped Snow while she was giving birth. And they were both part of the discussion at the war counsel. I think i like the idea that the dwarfs go with Snow and Charming once Snow wakes up from being in the glass coffin. Though the Blue fairy is working with Snow and Charming also so that makes me wonder how that works exactly what with the dwarfs leaving the mines that make the dust for the fairies. And in this episode the Blue fairy tries to stop Grumpy from leaving, but in the pilot they are both working with Snow and Charming. Something must have happened there.
