My question is why didn't they give Tanya some of Skittles' sweat to run tests on. I get that she's a little off right now because of recent events but she thrives when she has something to do. Plus I think if his sweat is a link to the zombies in any way, she'd WANT to test it since she has/had the keratin levels in her blood.

I'm not upset at all about the questioning of Tardust. Riley and Burt don't even know what he almost did/wanted to do to Lizzy. If Riley KNEW what he did to her in addition to what happened to Angel...dude would be z-chow quick fast and in a hurry. That epi with Tardust and Lizzy is the only one I can't listen to on repeat. I have to skip it. That jackass deserves whatever Burt and Riley do.
