To avenge the death of his wife Astra, he orders three of Kara's friends- James (Brooks), Winn (Jeremy Jordan), and Kelly (Carly Nykanen) to jump to their deaths, knowing that Supergirl can only save two of them. Kelly ends up being the unlucky third one. Speaking through James and Winn, Non orders Kara to accept defeat.
