Clark struggles with the reality of Lois's cancer.
Tropes:
- Atrocious Alias:
- Kyle dubs Jon "Rust Bucket" while forcing him to wash the fire engine over and over. Jon earns himself a slightly better name by helping with Sophie.
- Jordan finds the "Lil' Kent" shirt Jon receives from Kyle in the end ridiculous, comparing it to a rapper moniker. Jon quickly gets back at him by saying Sarah likes it.
- Big Damn Heroes: Jordan saves his father from Onomatopoeia's attack.
- Calling the Old Man Out: Jordan calls out Clark for adding another lesson every time he finishes one. Lois later also calls him out on it. Clark admits he was wrong after seeing Jordan hit by Kryptonite blast and weathering it much better than he anticipated.
- Character Death: Deadline asks Superman to get him to Bruno Mannheim to help, but Mannheim refuses and Deadline later succumbs to the numerous tumors inside of him at a normal hospital.
- Double-Meaning Title: The title references the phrase "being of sound mind and body" used in relation to a last will and testament, which Lois insisting on making in this episode, and is suggestive of the sound-based supervillain Onomatopoeia.
- Dual Boss: In the Fortress, Jordan fights against simulations of Atomic Skull and Bizarro at the same time, tricking them into taking each other out.
- The Gloves Come Off: When it appears Jordan may have been fatally injured by a Kryptonite rifle, a furious Superman blasts the rifleman with heat vision. This is a rare example of that power being deployed against an opponent who lacks heat vision himself. When Supergirl deployed heat vision on her own show, it usually resulted in a Beam-O-War although one time she did destroy a robot with it. Similarly, on Smallville, Clark once blasted someone with heat vision and was only prevented from killing him by the last-second arrival of another hero. It isn't clear whether the rifleman's armor enabled him to survive the blast, as Superman only hit him with a short burst rather than a sustained beam.
- Green-Eyed Monster: Jordan is dismayed to hear that Jon hung out with Sarah.
- Heroic Willpower: Despite being fired at not only by Onomatopoeia, but also by three Kryptonite guns, Superman fights all the way through and they can only manage to pin him down. They probably would have killed him eventually, but they're clearly shocked by the amount of punishment he's able to endure.
- Hybrid Power: Jordan is less severely affected by Kryptonite than his father. Clark even muses that Jordan might potentially surpass him because of his human ancestry rather than in spite of it.
- Hypocrite: Mild case, but Lois accuses Clark of trying to teach Jordan how to react in worst case scenarios, while he himself refuses to acknowledge the worst case scenario for Lois's cancer treatment. In the end, he admits that it was a coping mechanism.
- Internal Reveal: Lana finds out that Kyle and Chrissy have been seeing each other.
- Leaning on the Fourth Wall: Sophie states that everyone always forgets about her. In the context of the series, she has up until now been a Satellite Character to the rest of her family, each of whom have their own individual story arcs, while she's just been kinda... there, to the point where it's likely many viewers can often forget she even exists.
- Lured into a Trap: Onomatopoeia fakes Lois being in trouble to lure in Superman, then Mannheim's goons attempt to kill him with Kryptonite lasers.
- Made of Iron: When Onomatopoeia takes a super-speed hit from Superman after the ambush fails, she is still able to report back to Mannheim, all the more surprising given The Reveal at the end.
- Mirror Character: Clark Kent and Bruno Mannheim. They're both trying to save the people they love, and failing time and time again, never giving up. Clark initially with consulting his mother's A.I. and offering moral support, whereas Bruno is knowingly engaging in criminal activities to find a cure for his wife.
- Official Couple: Chrissy and Kyle decide to become one of these at the end of the episode instead of sneaking around.
- Papa Wolf: Superman is held down by Onomatopoeia's sound waves, but when Jordan is hit with a Kryptonite blast, he powers through and punches her out.
- Pop-Cultural Osmosis Failure: Lana's BurgerTime reference flies over Sarah's head.
- Relationship Upgrade: Kyle officially asks Chrissy if she wants to be his girlfriend and she accepts.
- Rousing Speech: A brief and to the point one. Hearing that Superman is in danger, Lois orders Jordan to go rescue him. When Jordan points out that his father says that he is not ready for this kind of thing, Lois tells Jordan to prove Clark wrong and go save him.
- Toxic Phlebotinum: The Super Serum gave Deadline powers, but it also gave him numerous tumors throughout his body, killing him. Ironing out this particular defect is Mannheim's goal, so he can cure his wife.
- Tropaholics Anonymous: Clark attends one for the relatives of cancer patients at the start of the episode, but initially doesn't plan on returning because he is refusing to consider the possibility that Lois might not make it. In the end, after facing the reality that it might happen, he goes back and takes it seriously.
- The Unfavorite: How Sophie feels and why she runs away. Jon sympathizes with her over having felt similarly in the past and convinces her to reconcile with her family.
- Unholy Matrimony: Peia/Onomatopoeia and Bruno Mannheim are married.
- Villain: Exit, Stage Left: Onomatopoeia disappears while Superman is busy tending to Jordan.
- Wham Shot: Onomatopoeia removes her mask and beneath it is Peia, Lois's fellow cancer patient and the reason Mannheim is trying to develop a Super Serum.
- What Happened to the Mouse?: Wolé Parks (John Henry) and Tayler Buck (Natalie) are inexplicably completely absent from the episode and not even mentioned; notably, the idea of them being the ones to save Superman in the climax isn't brought up at all. Justified, since Lois knows that he is in trouble now; by the time she calls them, tells them the problem, they scan for Superman, and fly over there, Clark might well already be dead.
- The next episode implies that he was in New Orleans, setting up defenses for his alternate self's family. This would almost certainly put him too far away to be any good.
