Joe was really amazingly relaxed for a tiny, teething baby who had just met a new person in a metal suit, which probably had a lot to do with what crazy shit he must have been exposed to in utero. He might, by virtue of being such an early-Sphere-adopter and Avenger legacy, have to be the most chilled out human being this side of the sun. Or maybe it was a good day. He leaned against Tony's shoulder as Tony hiked him up, grabbing at his neck and the entrancing lights there. "As stunning in almost every single way as my closest friends are, none of them have quite the right kind set of skills to make something like this happen," Tony pointed out. Most of the Avengers, himself included, could barely boil water, nevermind create and raise a whole human. That was what Jarvis was for. "Seriously," he continued, looking back at Joe now because he had discovered the beard, very curiously like the one on that very large, angry looking fellow, "lookin' after you is the bravest thing I can think of. Not just anyone is doing that. Cap would jump into a dinosaur's mouth before he raised a baby, wouldn't he?"
