Bruce lets out a soft sound of acknowledgement to the words, but doesn't say anything else beyond that. Christmas wasn't exactly a thing that Bruce tended to remember fondly due to his own personal experiences, but it wasn't as if Tony needed to hear that. He had his own things to concern himself with, after all.

So instead he just focused on watching their two Digimon frolicking around the snow and generally having fun. It was strange, watching them, seeing them alive and sentient. It was still hard to actually be able to equate them to actual, living beings, but with each passing day, it somehow got easier.
