I'd imagine that when Din and Grogu eventually reunite for the finale, Grogu is going to have a bit of a dark streak running through him, after all of the abuse he's about to endure. We see a little of it here in the finale, the way he is thrashing around the Stormtroopers. Din is going to have to show him the knob (and, perhaps, his face?) to start coercing him back a bit and snap him out of whatever hold Gideon has on him.
I expect a fair amount of Grogu torture next week, before Din and the gang are able to rescue him in the finale.
