quin has gotten a massive power up compared to what he used to be. even as a vampire lord at max strength he was nothing in comparison to what he is now. but he's still just as cocky as ever thinking he can just put Ray in timeout like that. this man just don't know who he's messing with. but I'll give it to him though an got some balls. might not be the brightest in the world but he got some balls.
So my guess is that Chris took a person's entire life force along with their Qi. It makes me wonder if Layla did the same or if she could use her talent at Qi draining to only take a little from many people for the same the effect or if she just used beasts. Also makes me wonder how life drain would work on full blooded vampires would it take their blood energy for the same effect.
