Okay, so I know Peter used Lydia as his plan B. He knew she was immune and wouldn't die from the bite, and him biting her connected them so that he could use her in season 2. But here's my question. HOW?? I don't think I've ever figured that out. How did he know that she was immune? Jennifer is the one who revealed to Lydia (and us) that she was a banshee. Did Peter know that all along? As an alpha, could he smell it or something? Since she's connected to death, he knew he could use her to come back to life? But I'll say it again. HOW?? If he needed a banshee, why Lydia? He was next to Meredith in the hospital. Could he not get to Meredith while he was getting revenge? Am I thinking too far into this? Probably. 😂 This is just another plot thingy I hope to know before the series ends but probably won't.
