JoJo's Bizarre Adventure - New friend

Makes sense.

Some cultures have the "counting coup" thing, where winning a severely handicapped fight (like touching an armed enemy like the original counting coup, or bringing a fist into a knife fight) the winner, if sparing the loser, has "I can get you anywhere anytime, don't fuck with me" rights.

Jonathan could take on the entire Shrek Street anytime he wanted without Hamon (don't forget Barry), but he still offers forgiveness and friendship instead of the usual "don't ever fuck with me again, bitch".

Speedwagon was savvy enough to know that if he ever met such cinnamom bun, he was a friend for eternity.

"He is surprised at almost everything I and others do around him."
