Not only is Earth-2 Iris a cop, shes also the wife of Barry Allen! In a case of what couldve been for Earth-1s Barry, he gets to have Iris as his other half, even if it is in another world. Regardless, the two certainly make a great couple and have some great moments together here, even if the Barry Allen involved is totally not this worlds Iris actual husband which makes things a tad creepy. Oh, and in another WTF twist, this world, as demonstrated by Iris, has a meta-human alert app in full working order. Back on Earth-1, Cisco has recently created something similar, but this technology seems to be commonplace in this alternative world.
