^I expect one of 2 things will happen with Cardin after V3:
1. He'll become less of a prick by necessity/experience; With fewer training facilities, it'll be hard for him to gain experience outside of unmitigated combat risk, it'll be do or die, meaning being a dick to teammates would likely get him killed or lose him friends.
2. He retires/drops out of training, possibly become a low level merc, in which case Velvet will become even more of a superior to him, making him less likely to be able to bully her in the first place.
