The First and Last

Finn lived in National City her whole life. After being recruited by the DEO, she meets Alex Danvers. She quickly falls for her. She finally tells Alex and they date in secret for a short time. Why so short? Alex thought Finn was dead.

After falling into the hands of some strange organization, she's sent to earth-1, sent back in time and wakes up in the past. She's rescued by The Legends and works with them for a short while. She then goes to Central City. She decides to go back to Alex. The problem? The last time they'd seen each other was two years ago.
