Bruce let out a small, amused sound at Tony sniping about the D-Streams, although he couldn't be too surprised - after making something like the Iron Man suits, having to handle something as seemingly low-tech as the D-Streams must be some sort of insult to him. It wasn't hard to understand where his frustration was coming from, when he looked at it from that angle.

He thought about it for a moment, over Floramon's shout of "Yeah! I didn't know snow is this fun!" back to Dorumon as the two Digimon play in the snow.

Eventually Bruce just hitches a shoulder, glancing at Tony and then to the D-Streams the both of them received. "Maybe they'll only be available after Dorumon... ah, 'digivolves'? It seems to be a thing here, after all." Not that he was certain, but it was still a theory nonetheless.
