I realized that Joey and Henry's relationship in BATIM reminds me of Ub Iwerks and Walt Disney, but the difference is that Walt and Ub become best friends again, while others don't. Ub protects Walt because he doesn't want Joey to give Walt bad ideas. XD
Realistically Walt and Ub never were besties, I'd say Walt decided he wanted to be Ub's best friend and Ub had no choice. When they got older they learned to forgive and appreciate one another, after Walt finally decided to not be petty anymore lol, they were just reacquainted.
Unfortunately I don't think Walt had many close friends because of his arrogance, but I'd argue his best friend was his brother Roy. And his longest/oldest friendship is Ub.
