Io

Tony and Peter arguing and Peter just gets so angry he starts yelling at Tony in italian

Peter: non sono un bambino, ok?! Sono un adolescente che sa prendersi cura di se stesso!

(I'm not a child, okay?! I'm a teenager who can take care of himself!)

Tony : NO! sei il mio bambino che non verrà gettato a 20 piedi da me in un fiume dove non puoi termoregolarti!

(NO! You're my baby who won't be thrown 20 feet away from me into a river where you can't thermoregulate!)

Peter: you think I'm your baby?

In Tony’s cabin in Endgame, I noticed that the chairs Tony and Pepper have don’t look very comfortable (to me at least). But knowing Tony I’d say you could give him a stump to sit and he would be happy with it.

Or, actually, he would prefer sitting on the floor…
