look at his little hands!
I love how stitch has a habit of grasping at things when hes anxious. One of my favorite parts of the movie is when hes standing in the wreckage of Lilos home, with nothing left to destroy and Jumba comments that he never gave stitch a greater purpose than to destroy. “What must it be like to have nothing, not even memories to visit” and Stitch is looking around and clenching and un-clenching his hands.
Its a very nice little habit that they gave him, especially since hes so smart but doesn’t talk much. It gives him a sort of human anchor, something that ties him to us and gives us something to recognize and read.
