Listen! I watched this on Hulu, and the scene opening with Amy breaking down into tears after Brad killed Winston? I was crying with her. Amy is only 10, and she had been through a lot even before she was kidnapped (speculation on my part since her mom was a drug addict). And then all this craziness with the vampires and doctors playing God. Then Brad's voice kind of breaking when he told her, "I don't want to lose you" and I cried some more. I confess that I did chuckle a little bit at Brad's hurt face when, earlier in the episode, Amy was all, "You're not my dad, you're just some guy who kidnapped me!" because she was upset over the book and not being listened to. Whew, kids can cut to the quick when they're in their feelings! Kudos to Saniyya Sidney because usually kids being kids annoy me on TV shows.
Although everyone was rightfully called out on their shit in this episode, I still feel sympathetic to Sykes because she seemed to be the doctor who wasn't doing this for personal gain or ego boost. I assume all of the death row inmates were of age, so they had the right to consent to being part of the experiment. They were persuaded, not coerced. Was it deceptive, absolutely. But, while I disagree with them being guinea pigs, it's hard for me to feel that sorry for them. At least Carter is innocent of murder, but he still consented to be experimented on. Amy didn't have that choice, and even if she did, she's not old enough to consent anyway.
To me, the person who made a really stupid move in the episode was Lila when she saw her kidnapper murdered. I assumed the keys were still in the ignition when the guy got out because the headlights were on. All she had to do was hop in the driver's side and drive off. I sure as hell wouldn't have gotten out of the car, at least not right away.
As for the vampire science on this show, it seems to go however the episode plot decides, so I don't think too deeply about it. I'm interested in this show for as long as Amy and Brad are the center (with Lacey supporting). If that ever changes, I'm happy to move on.
