Well we're here, why not? xD Yeah not an abusable skill by Xano, just something he has in bad spots, and even then its not as ridiculous as the witch from the original series. Mako got it because whatever I guess, I don't think the creators even bothered to really set into stone WHY people can suddenly do this when it took insane levels of skill to grasp in the first series, but then again they didn't care about a lot in Season one, as they didn't think they'd get more seasons. Asami can probably work on it but it probably takes months on months to fully control. I could see her doing it in her berserk mode and mortally wounding Mako :O 

We can ignore it, no problem, gonna decide how to make her life hell next xD
