YOUNG JUSTICE (OUTSIDERS)

SEASON 3: NEVERMORE (2019)
In this final episode of the series, as the heroes gather at a diner (Bibbo's), a pony-tailed blonde waitress brings coffee and refills cups. She is shown wearing a Legion flight ring, implying she is in the present for a reason, perhaps with other members. It foreshadows the appearance by the Legion in SEASON 4.
