Well, you could promise him that next time he can be a triton. And, just to throw him a bone, have the campaign be one where being a triton is useful from time to time - river travels, ruin on a island, that kind of stuff.
Yeah, I suspect that's not the problem.
Anyway based on feedback I said he can hexblade but not allowed to MC it, plan B no Hexblade.
