Peter claims that Lindsay was stoned after drinking the couple's mushroom wine and eating the mushroom pasta.
How could Connor's duplicate look like him while Lindsay's duplicate didn't look like her?
In this episode, parts from the closing scenes from "The Perestroika", The show's 1st season finale, are seen in the second time since the show started. Those are the same parts that were seen in "Threads", the second season's first episode.
How can Vince care for Lindsay one moment and then not care for her in the other?
Except of their kiss in the beginning of the episode, the relationship between Vince and Lindsay doesn't look very good. They fight all the time and he doesn't really care for her. Is this how relationships look in an alternate timeline?
The episode is about time travel, but the events in the episode look more like an alternate time line (In the regular time line, Lindsay isn't married, the justice system doesn't look the way it is, freedom exists etc.)
Lindsay's husband, Vince didn't really seem to care when one of the cops told him on the phone that Lindsay was dead. Earlier on the episode, he told the cops that he didn't care for the lives of any of the people in the vault, but Lindsay's.
