User blog comment:Hidden Scorpius XI/My impressions on Volume 4, Chapter 6 (Tipping Point)/@comment-7622429-20161212194345

I brought this up in another place on the internet, but think back guys, knowing the info we have now. Tyrian was originally supposed to go after the Spring Maiden, right? Well, if we assume he wasn't supposed to kill her and just bring her to Salem like with Ruby, well, it can't exactly be easy.

Maidens are powerful, and I doubt you could just keep her in a net or sack, with the same sort of thinking applying to Ruby. Now, we have this episode. Tyrian, a scorpion Faunus, whose eyes changed to purple briefly before attempting to sting Ruby. I think this is our indicator of how he was expected to bring the Spring Maiden initially, and now Ruby currently, to Salem.

A scorpion's sting is venomous, and, even if not lethal, can still have some nasty effects on the unfortunate victim. Why go through the trouble of knocking out and restraining a flailing target when you can just incapacitate them with some venom instead?
