For those not aware, CBS opted to skip the fourth episode of Supergirl, instead delivering their Thanksgiving Day-themed Episode 5 a week early. The reason for this is down to the recent atrocities in Paris, with the skipped episode supposedly having heavy focus on explosives. So, here we are: Livewire. This latest outing for Kara Zor-El features problems for both day-to-day Kara Danvers and also her superhero alter-ego. For Kara, she has to deal with the arrival of her foster mother, Eliza (played by former Supergirl, Helen Slater), which brings the usual drama so often associated with any sort of family gathering that features alcohol. On the Supergirl front, the big threat this week is the titular Livewire, a radio DJ with a grudge against Supergirl, who just so happens to end up with her own electrifying powers. By the time that the episode came to a close and Livewire had been shut down, viewers were left with a whole host of questions.
