When Ralph Dibny discovered traces of dimethyl sulfate in Cicada's mask and found out that Szrek Chemicals uses the substance in most of their products, the he and Harrison Sherloque Wells went to a Szrek Chemicals site in Central City. Ralph asked an employee about the mask, only to learn that all the employees in all Szrek Chemicals facilities wear the same kind of mask, and that they're not the only facility who uses them. Ralph and Sherloque then left, though not before Orlin spotted them.
