The Hulk takes note of Flower Man's name but no, so far the only person who the Hulk calls by his name is Tony. Still, he'll remember Flower Man's. The more the Hulk sits with him, the more relaxed and happy he is to be here, without any of the dizzying pull that usually means he's relaxed enough for Banner to come back into control. Banner hasn't been fighting him, and the Hulk knows it's because there are people hurting other people; he knows Banner is afraid, and that he's hiding behind the Hulk. He doesn't mistake this as acceptance on Banner's part.

Anyway, Flower Man and his flowers make the Hulk feel good, happy, and his mouth twitches into a smile.

"I'm glad I didn't smash you." He's kind of saying sorry, and he is sorry; expressing himself isn't his strong suit.
