Bruce being accepted on Asgard and being shown not just begrudging respect, but reverence for Hulk’s strength and might in battle (perhaps even mightier than Odin’s own Berserker army). Bruce feeling loved by his new friends. Hulk having actual friends of his own!! Bruce feeling at peace and relaxed in his new environment, as any Hulk-out would almost certainly result in jovial greetings from Hulk’s friends and some rough horse-play, rather than persecution and destruction and pain. Hulk and Bruce’s relationship improving. All of the Bruce’s relationships with his other alters improving. Bruce exploring eons’ worth of knowledge of magic and using that knowledge to draw scientific parallels and make new discoveries in Midgardian science (the hand-flapping when he comes across the libraries). Bruce and Hulk being happy on Asgard and finally experiencing the peace they’ve deserved for so very long.
