Well, there are all sorts of different sorts of change (and non-change) going on in comics, but it's definitely true: when I read those issues, I was quite startled to find out how *immature* Cap came accross back then--plenty of times it was Wanda or even Pietro who had to pull Cap and Hawkeye apart from their bickering. (When Pietro and even Wanda weren't joining in, that is.)

Which is not at all how that dynamic would have gone these days.
