This set of pics from Supergirl 2.10 “We Can Be Heroes” reveals that an old villain is back – Livewire. And from the number of pics of Kara and Mon-El together we gather it must be a pretty big episode for them too. Anyway, here’s the official synopsis: “After Livewire (guest star Brit Morgan) seemingly breaks out of prison, Supergirl (Melissa Benoist) is intent on recapturing her. After training Mon-El (Chris Wood), Supergirl takes him with her when she sees Livewire attack the NCPD but things go awry when Mon-El puts Supergirl before the citizens of National City. Meanwhile, James (Mehcad Brooks) decides to come clean with Kara, and M’Gann (guest star Sharon Leal) has a psychic attack and collapses into a coma.”
This episode airs in the UK on 7 February.
