Only time will tell if Supergirl and The Flash go the romance route for Kara and Barry.
Theres no saying how long Supergirl and The Flash will last on The CW, and anything really can happen.
Interestingly and somewhat amusingly Kara is the second bespectacled blonde that Barry has befriended, rather than wooed, since The Flash premiered in 2014.
Comic TV shows are all the rage, and theres no hotter place for superhero action than The CW.
