Lena (Katie McGrath) was pulled into the spotlight when children were diagnosed with lead poisoning on the latest episode of Supergirl.
Morgan Edge (Adrian Pasdar) blamed the device that Lena used to get rid of the Daxamites putting Lena’s life in danger. Kara (Melissa Benoist) stepped in to get to the bottom of what really happened and with Sam’s (Odette Annable) help she discovered Edge had contaminated a public pool.
Lena attempted to confront Edge but was knocked out and woke up strapped to a plan containing barrels of the chemical. Edge was trying to contaminate the water supply but Kara stopped his plan.
Meanwhile Alex (Chyler Leigh) and Maggie (Floriana Lima) tried to save their relationship but ultimately made the painful decision to split up.
Elsewhere Sam was shot but realised that the bullet didn’t injure her.
The next episode of the season is Midvale. Kara heads home to Midvale. But all hopes of some R&R are dashed when her visit forces her to recall a painful childhood memory.
