Dale's hurt and tearful expression when Chip scolds him in "Le Purrfect Crime". It's no wonder the poor guy became Ramdale in that episode.
Chip's Disney Death in "Seer No Evil" and the other Rangers' tearful reactions as they gather around Chip's hat which Zipper has just pulled out from under the treasure chest which has apparently fallen on Chip:
In issue 4, Fat Cat uses the ARS signal to the Rangers so they can finish eachother of. Monty breaks out of it, thanks to his cheese attack, but he is soon on tears when he sees the Rangers fighting.
Monty: Mates, it tears my little heart in two to see us fighting like this. I guess I could make a speech here, saying how much we mean to eachother, about what we've been through. But I know the ARS does the number on ya, so you may not hear it. Still, in case there's a part inside all of ya that's still there, still the team I love, I say STOOOPPP!
