This is...beautiful. To say the least. Witnessing a wellspring of human emotions like this made him feel good. Like he'd connected with something human again. However briefly.

"It looks like he's calmer with you. Which is good." He doesn't smile well, still, big green and brown roots curve upwards in the best attempt he can manage, "I'll let the two of you get reconnected in peace. Stark, I've got something for you but I'll bring it by tomorrow."

Studying Bruce, trying to picture him as a large big green creature and failing. It's difficult to picture.

He gestures, "Mr. Bruce? Or Bruce? - I don't - if you ever want to talk to me about it I can...well. I'd be happy to lend an ear. Until then."

Feeling positive, indeed, feeling peppy he turns to go. It feels like he was re-planting roots in a world he'd forgotten.
