[Rick and Morty] is there something different in the relationship of the Rock and Morty from Earth dimension C137?

In Close Rick-Counters of the Rick kind, we see that C137 Morty is much more brave than any of the Mortys held captive by Evil Rick. Is MC137 special to R137?

Yes, it is shown that C137 Rick is one of the only (if not the only) Rick who values / loves his Morty. He's not great at showing it, but he demonstrates it numerous times in the show (the King Jellybean episode is a good example).

As for Morty being more brave, there are a couple of theories. He is either the prime Morty or his personality is just different in that way. Personalities can vary in the multiverse to an extent so it's possible he is the bravest one out of the ones we have seen so far.
