Lanterns Just Answered A Major Superman Mystery

Lanterns exists in its own corner of the DCU, with a grounded, more serious tone that stands apart from the lighter, more irreverent style seen in the likes of Superman and Supergirl. It would be quite the surprise, for example, if John Cena's Peacemaker ever made a cameo on a show as dark as this one. Having said that, Lanterns still has connections to the wider DCU, and Episode 5 appears to answer a major question fans have been asking since, well, essentially since the franchise began.
