Shows like Supergirl have a history of casting actors with a super-affiliation in roles. Dean Cain (Lois & Clark: The New Adventures of Superman) played Kara’s adoptive father while Erica Durance (Smallville) played her Kryptonian mother, for example. Superman & Lois is following in Supergirl’s footsteps, also incorporating nods to previous super-shows and movies. CW’s newest take on Superman and his family honors the versions that came before. The font used for the town name of Smallville is the same as what was used in the credits of the previous television incarnation. Bitsie Tulloch regularly gets the wardrobe department to incorporate animated and comic book looks into her version of Lois’ wardrobe. A recent episode of the series also provided a nod to a ’90s TV series with the introduction of a new character.

Episode 8 of Superman & Lois, called “Holding The Wrench” explored the feelings of inadequacy in a superhero household. Jonathan found himself upset that he had no way to defend himself against Superman’s enemies. He ended up in serious danger as a result. Lois had to deal with her own fear when it came to the potential of losing a child. Both of their emotional storylines provided the backbone of the episode. That’s a marked change from the season so far which otherwise focuses on Jordan Kent’s burgeoning powers. Sam Lane set out to interrogate John Henry Irons amongst the emotional storylines.

Both Superman and Sam attempted to talk to Irons about just what he was up to in Smallville. Neither conversation went the way they wanted it to. In fact, Irons didn’t last long holed up in interrogation. Instead, he broke free from his restraints and went up against several soldiers, getting himself to a room full of experimental Kryptonite. His goal? To find a weapon to use against Superman. It wasn’t until he was ready to kill Superman that Lois intervened. The Easter egg came into play before that intervention: when he was going to be interrogated.

One of the soldiers Sam Lane worked with had the surname “Trask.” Trask wasn’t one of the soldiers tasked with guard duty or observing those in custody. Instead, his specialty was in interrogation. He told General Lane that he would have his “equipment” ready in case Superman couldn’t get Irons to talk.

Superman was vehemently opposed to the implied torture, but the audience didn’t get to see Trask much after that. That’s because another soldier killed him in an effort to get to Superman. That soldier was part of the larger Morgan Edge storyline, making the Easter egg a casualty of the ongoing storyline. Though Trask didn’t have a huge part, longtime fans of Superman would have recognized the name. He didn’t originate in the comics like so many of the characters planted as Easter eggs. Instead, Trask’s connection to the Superman mythos came from the ’90s series Lois And Clark.

In Lois & Clark, Trask had almost as small of a role in the overall series as he did in Superman & Lois. There, however, the character appeared in two episodes of the series as an employee of a secret government group. In fact, Trask helped found Bureau 39 in the effort to stop extraterrestrials from taking over the planet. He believed Superman was the first member of an alien invasion force, not unlike John Henry Irons’ belief that Superman will eventually turn on humanity in favor of the Kryptonians.

Trask actually discovered the spaceship that Superman made it to Earth in. He also obsessively researched Superman. Trask made it his personal mission to track the Kryptonian and it made him a liability to the secret organization. He also discovered the rock that would become known as Kryptonite for the series. This version of Trask even discovered that Superman and Clark Kent were the same person -right before the series killed him off. Despite not appearing much in the show, Trask was instrumental in bringing many aspects of the Superman mythology to the series.

Fans can keep a lookout for more Easter eggs as Superman & Lois already has a season 2 renewal.
