[MCU] Did Tony Stark have a contingency plan if Peter Parker had responded violently to his intrusion?

Stark shows up in his apartment, macks on his weirdly attractive aunt, and then reveals that he knows about Parker's extracurricular activities, which kind of freaks Peter out. Did Tony have a backup plan (beyond "get beaten to death") if the kid who could catch a car in mid-air had gotten violently defensive of his secret identity?

Besides shouting at him to stop before threatening to unleash his Iron Legion on him and his aunt? Probably not much. He'd activate his watch gauntlet device to at least have some defense and offensive capabilities, then stall for time and evade (it helps Peter is trapped inside, lots of obstacles) until he can get some more Iron Man parts. Then he can get outside for some space, and contend with Peter on equal (if not pro-Iron Man) terms. 

But he did his research. Peter is a pretty chill kid, and he would either try to lie to Tony about it or he would panic and anxiously demand to know what Tony is going to do with the information or what he wants with him. Peter isn't the kind of guy to flip shit and kill a guy, especially not a fellow hero that's saved the world a few times. You can tell from their interactions in Civil War and Homecoming that Peter sees Tony as an idol of sorts. How could he not? Successful genius who tinkers with tech and also helps save the world? Father figure he never had. Peter wouldn't attack Tony, certainly not full force unless Tony snapped and killed one of Peter's friends or Aunt May. Tony was at very little risk.
