SUPERGIRL | Sky1 8PM

If you’re a fan of the DC Comics universe, keep your evenings free this week as Supergirl, The Flash, Legends Of Tomorrow and Arrow return to our screens for some 8pm heroics from Monday to Thursday. Our first destination is National City, where Kara is trying to keep her heartbreak at the loss of Mon-el at bay by throwing herself into her superhero work – but who’s the citizen with a mysterious connection to our heroine?
