Warning: This article contains SPOILERS for Superman & Lois season 4, episode 7.Superman & Lois season 4 introduced a major character from the comics with a twist, and after an initial conflict, the DC series found the most shocking way to resolve Clark Kent’s latest problems. As this is Superman & Lois‘ final season and the show suffered budget cuts, it was not expected that many new characters would be popping up throughout the series. That has been true for the most part, with Superman & Lois season 4’s roster of characters sporadically using main stars from previous seasons and not having many major characters.
