On the list of things that would make me flip my lid, running into Robert Downey Jr. buying Avengers back issues is pretty high up on the list.
That's probably right behind "ScarJo buying back issues" and "Gene Hackman buying back issues of Superman", but for very different reasons.
Also behind this link to Bleeding Cool? Whatever happened to The Star Wars Kid? All I'm saying is: it explains a lot about Ransom.
