Fosnight (Earth-90)

Fosnight was a con artist and secretly a police informant.

Early Life
At some point, Henry Allen saved Fosnight's life, and he had a "life debt" to him and to his two sons.

The Fires
In 1990, Fosnight was witnessing a fire and had a talk with Sadie Grosso while pick-pocketing someone next to him. They were interrupted by a detective that was filming the scene before witnessing the Flash's appearance. The next day, he would be scamming a group of people with a card trick, but Barry Allen came and interrupted the fraud and asked questions about the recent fires. Despite not being aware about any information regarding the fires, Barry told him that if he finds anything, he should call him right away. The next day, at night, Fosnight recognized Noble John Spanier an arsonist that killed Arthur Simonson's father fifteen years ago. He calls Barry and told him that he spotted him at the old customs house.
