Supergirl and the Legion of Super-Heroes # 23

The Legion take Supergirl to Rokyn, a place where Kryptonian descendants live now. Rokyn used to be the bottle city of Kandor. The Legion brought her there so she could realize that she isn't dreaming everything up, the Legion is a reality. While on Rokyn, the Legion try to stop a heist on a museum, a heist that includes Jeyra Entinn and Polar Boy. During the fight, Saturn Girl picks up a stray thought somewhere and it's revealed to be Mon-El. Meanwhile, Element Lad and Triplicate Girl go underground to see if the machine rising from months ago has completely been quelled. While there, Triplicate Girl comes across a boy named Plant Kid and brings him to the Legion. However, Plant Kid has ulterior motives.
