susieb, thank you so much! I'm really glad you liked it.
Jenna, hmmm...those are very interesting questions! Personally, I shy away a bit from the "smell the past, glimpse the future" thing. To me, Mick uses his "vamp chemical lab" nose and his detective skills to determine what happened, but I don't really think of him being able to picture the exact sequence of events as if he had ESP. But many people do interpret it that way. To me, it goes kinda like this, in his head: "Hmm... blood and brain matter. Smells like eyeball, too. I bet he got the guy right in the shades." (Eew... sorry...)
I'm not sure it occurred to Mick that Beth might think he and Leni were dead. There was no indication of that in the show, anyway. My take is that he was focused on getting in touch with Beth--both to confirm to her (and Josh) that the leak was real, and to seek her help to get out of that terrible situation. Maybe he hoped Beth would realize that he needed blood, and bring some with her--although how he thought she'd get it is a bit of a mystery. She didn't know about Guillermo, just that Mick had a connection at the blood bank.
Actually, I don't think he was in any shape to think things through rationally by then. He just needed Beth. "Only Beth." She was the only human he could trust, the only one he
knew would come, if only they could reach her. I'm not sure he could think any further than that.
