- —Jay Garrick warning the team[src]
Jay Garrick is a mysterious man who knows the identity of The Flash.
While Barry Allen investigated a crime scene, Garrick watched from a distance and took pictures. Jay later appeared at S.T.A.R. Labs, getting past all of their newly-installed security, much to the shock of Barry Allen's team. Garrick gave his name and revealed that he knew that Barry was The Flash. He then claimed that their world was in danger.
