Okay, so, the plot of that part of Avengers v4 is that the Infinity Gems are being stolen, and Steve and a bunch of Avengers show up in the Himalayas to look for a Gem, whereupon they find Tony and the Illuminati also looking for the Gem, because it turns out that the Illuminati exist and also had (or thought they had) the Infinity Gems. This makes Steve mad, as we see in Avengers v4 #9:
They do in fact have a screaming fight in the snow, surrounded by all their friends:
I’m particularly fond of Commander Steve “No Chill” Rogers screaming YOU THINK THIS IS ABOUT MY FEELINGS? at Tony, who is like “…yes.”
I have omitted the pages in between, which were about everyone else standing around watching them fight and speculating about their relationship, but you should know that we get this line:
The serum amplifies everything that is inside, so good becomes great; bad becomes worse. This is why you were chosen. Because the strong man who has known power all his life, may lose respect for that power, but a weak man knows the value of strength, and knows… compassion.
Despite Iron Man having left the team Tony Stark is still helping when Cap and the Avengers need equipment. He seems distressed when Cap shows his doubts in the new team and gives him a pep talk.
Avengers V. 7 #1.1 (Set during and after Avengers V. 1 #16)
remember when we were ready for a major throw down here but instead of taking his anger out on Gamora he understood that she was not her father and sincerely emphasized with her pain? yeah. this is why i love Thor
