Details rediscovered the next time around.

In the five Doctors they kept calling Doc #5 "the kid" or "the young one" or things to that effect, and they treated Doc #1 as the wise old man, instead of the arrogant youth he likely would have been seen as (imagine you are 72, and and meet yourself at ages 54, age 36 and age 18. You'd probably find your 18 year old self an insufferable youngster, and your 18 year old self would probably think he's more clever than the lot of you combined.)

Given how young the actor who played Doc# 5 was, it would have been really funny if the other Doctors all called him an old geezer, and treated his young body as signs that he's having a sad little midlife crisis.

On the other hand, when First Doctor first showed up in the Fifth's TARDIS and started tramping around like he owned the place, Five mentioned to Tegan as an aside that he's mellowed in his old age.

Did he? Sheesh, it has been too long since I've watched a couple of these episodes. That is a cool line.

It was like that in The Three Doctors too - Hartnell is the wiser, older Doctor who tells the other two what to do. "What's a bridge for eh?"

doesn't the 3rd doctor in the The Three Doctors say about the first "I always had a great deal of respect for him"?

Yeah, again this was my feeling that in this early days they weren't entirely sure that each Doctor was the same person. They treated it more like reincarnation.

In that same episode, the 3rd Doc doesn't recognize the 2nd Doc's recorder, just says it is strangely familiar. By modern Who standards, he'd know what it was, even if he didn't want to play it anymore.
