Now that I think of it, I think it's a paralyzing poison.

Notice when Tyrian was about to stab Ruby in the previous episode, his eyes turned purple too, and we *all* know he didn't intend to kill her.... so my guess is he wanted to paralyze her.

Also, for the next episode, Qrow will probably go K.O. the next episode to "shock" the audience, thinking he's dead.
