It could not be ignored, in fact it had to be addressed, and unfortunately, if Tony was too distracted to remember what he had done with the cream, Peter was clearly worse. Without looking down, still focused on Peter like they were having a perfectly normal conversation and Peter wasn't actively trying to make his own life worse, Tony snatched his wrists and replied, "You tell her to do something else that isn't that." This seemed like an obvious solution to Tony, so he had to come up with the reason this would not be so obvious and landed on, "Unless she really likes doing the Baby Monitor thing...," which he supposed would make for a more difficult conversation. He didn't get much of a chance to reflect on exactly how much of a pushover he would personally be in that situation, because it finally struck him, "Wait, did I make your suit? You let me make you a suit?"

Peter didn't even let Tony look at his suit. Other-Peter.
