Harley Quinn Smith revealed via her Instagram account that she would be stepping onto the series during her father’s (Kevin Smith) upcoming episode, ‘Supergirl Lives’.
Odds are, that’s all Harley Quinn Smith will be doing: a similarly small role during ‘Supergirl Lives’, meant as a fun “Easter Egg” for Smith’s fanbase.
Now it seems viewers are in for yet another guest star within the universe, this time with Supergirl being the recipient.
That being said, Smith’s longtime collaborator/friend, Jason Mewes (aka the Jay to Smith’s Silent Bob), made a short-and-sweet cameo in Smith’s The Flash season 2 episode, ‘The Runaway Dinosaur’.
