Do you think Caius and Jasper would get along?
This friendship(?) is very much a thing in fanfiction. Usually, it’s presented as a game-recognizes-game scenario. These two vicious, warlike characters acknowledge one another’s ability, and a bond of mutual respect grows between them. Personally, though, I just don’t see it.
All the stuff which humanizes Jasper– his devastation as a result of the Southern Vampire Wars, his lessening ability to enjoy human blood– would make him seem like a coward to Caius. I mean, Caius’ response to his own psychological scarring is more violence, not less, and he has no patience for vegetarian vampires as a whole. Even Jasper’s military skills would strike Caius as insignificant because he couldn’t maintain them.
Meanwhile, the moments when Jasper really shines are fundamentally passive, but also humane and carefully-considered. Letting Peter and Charlotte go, trusting Alice, and joining the Cullens were these quiet, understated choices, not splashy action montages. Because he’s at his best when he’s not acting on his worst instincts and deferring to the needs of others, Jasper presumably wouldn’t have much respect for Caius’ reactivity
and terrible ideas.
