Superman and Lois season 3 episode 6 review


Starting off the episode with Clark in group therapy with the spouses of other people who are battling cancer is a brilliant way to set the tone for this episode. It immediately sets Clark at his most vulnerable and human by forcing him to confront one thing that he has no say over. Natural causes of death. So, when he goes to pick up Lois and says that group therapy “wasn’t for [him],” it’s simply heartbreaking because he’s just seeing the people that he doesn’t have the power to save. Clark is the strongest man in the world, if not universe, and yet, at the end of the day, he’s still immensely human, which we see in the first five minutes of this episode.

So, with Clark refusing to even accept the possibility that Lois may die because of her cancer, this leads to some obvious frustration between the two when Lois notices. She then tries to get advice from her new friend, whom she met during her chemo session (the same woman who spoke to Clark in the previous episode), which she does. And the answer isn’t a simply solution either. People, even Superman, are complicated, especially when confronting death.

Finally, she confronts Clark about this and, it takes a bit, but Clark finally realizes that his relentless optimism is actually toxic to both himself and his wife. Tyler Hoechlin plays this so beautifully and the way that he quietly says, “I don’t wanna lose you,” cuts so deep and feels so real.


As Lois and Clark are two steps behind whatever Bruno Mannheim is planning, his scientists begin to dissect Bizarro. This doesn’t take up too much time in the episode, but it leads back to the other overarching villain so far this season, Onomatopoeia.

Onomatopoeia is terrifying. She has been since her first appearance this season and very much continues to be so in this episode. While not like her comic counterpart really at all, that’s all for the best. Her design is disgustingly good and her powers are so eery and creating such an unsettling vibe to her scenes, which is all thanks to excellent sound design. When she uses Lois’ voice to ambush Superman, it creates such an unsettling sense of dread, simply through the sound design that Superman & Lois‘ audio team managed to create.


While everything else is happening around them, Jordan and Jon are both training, and struggling with their respective mentors.

Jonathan is frustrated about is time with Kyle down at the Fire Station simply because of the hazing that Kyle is doing to him which, literally is the most annoying thing to put a kid through. But this sets up the distance that Sarah, Kyle, and Lana have with Sophie and eventually leads to us actually seeing how much Jon has grown over the past two seasons with his conversation with Sophie. Seeing him acknowledge his mistakes, as well as his insecurities in order to show someone that’s hurting that they’re not alone, that’s exactly something that the son of Superman and Lois Lane would do.

Whereas with Jordan, Clark is scared for Lois and pushes Jordan very hard to be as prepared as he can be to go into the field, as he doesn’t want to lose him either. It’s a very human, and understandable, reaction for Clark to have. But, in the end, when Onomatopoeia has Clark on the ropes, Jordan goes to help his dad, regardless of what happens to him in the end.

In the end, Jordan gets blasted by a kryptonite shotgun point blank and it almost kills him, but it doesn’t affect him the same way that it does Clark, so he manages to shake it off. But this also gives Clark a wake up call to be a realist with Lois.

Superman and Lois season 3 begins and ends with a therapy scene this week and despite the heavy nature of those, it never once loses what has made the show so great.
