"Thanks," Bruce says, both in reply to being ok in Ben's book and for being handed his food. The huge burger that Ben got for himself earns a surprised eyebrow but nothing more. Bruce starts in eating hungrily with the appetite of a man twice his size.
There is a flicker of a smile at the orange soda comment that Bruce can't hide well enough. That was pretty funny. By the time they get to the mansion, Bruce has finished off most of his food and he was feeling a little more human despite his lack of shirt. "It's one of Stark's places, or so I'm told." Tony Stark never did anything halfway. Bruce cleaned up his wrappers, putting them back in the bag they came from so he didn't leave a mess in Ben's nice truck. "Thank you for the food. I'll...keep that in mind if I'm ever down that way." Hopefully as himself and not the Hulk.
Once he's out of the truck and back in the mansion, Bruce has himself a shower before falling into bed to rest. Quite a day this has been.
