Haven't seen it brough up yet, but remember Tyrian's sitting posture in the first episode? Now it makes perfect sense! He doesn't sit on his butt because he's got a big ass tail that he can't put too much pressure on.

Also, I'm calling it now as I did in another blog post:

Tyrian uses his tail's venom to incapacitate targets for live capture, like he was supposed to do with Ruby and presumably the Spring Maiden.
