Either Jesse and Barry are not familiar with Alexandre Dumas or possibly Dumas doesn’t exist on Earth-1 and Earth-2. That’s right, I’m calling it: the man in the iron mask is the real Jay Garrick. The man we know as Jay Garrick is an imposter. This explains his lack of speed without the influence of Velocity-6/7/8/9; he never had any in the first place.
Security in the Earth-2 version of S.T.A.R. Labs is much, much better than on Earth-1. Partly that’s because it’s a working facility with actual security guards, but it still has cool intruder alarms. Cisco should take notes.
I am loving the little throwaway lines and scenes that establish further that Earth-2 is indeed different from Earth-1:
[li]Patty Spivot is the CSI tech that worked on most of the Killer Frost cases.[/li][li]The mayor of Central City-2 is named Snart.[/li][li]Oliver Queen never returned from the island. It was his father that came back and became a hooded vigilante.[/li][li]Deadshot-2 can’t shoot straight.[/li][li]Singh-2 is not a police captain but a master criminal.[/li][/ul]
