Wells: Trina, you knew about the nanny cam, didn't you? You told the killer about it, you must have given him my key card, too. Trina: Mr. Wells, I-I wasn't even there that night. Dogget: The first thing you're supposed to say is "What Nanny cam?"
Merlin Sickness: Wells briefly experiences time backward, starting with the day of his death, every day he goes to sleep, he wakes up the day prior, with only memory of what's happened afterward and not what's happened before. He has no idea what's going on the day he dies, but by the day of his wife's murder he's figured out enough of what's happened to be able to prevent it.
