Insontis II is written by KCS Scribbler.
After Captain Kirk is returned to his proper age, the Enterprise locks in orbit to study the planet's age-regressing technology. The ship is thrown into this strange situation anew when Spock tries the same thing.
This fanfic contains examples of the following tropes:
- Baby Morph Episode: The premise of the fic is that Spock used the same age-regressing technique used on Kirk during Insontis.
- Baby Talk: McCoy decides against using standard baby talk, not wanting to be called "illogical" for it on the chance that Spock can understand more.
- Bash Brothers: Groping for a Vulcan term to explain his and Spock's relationship, Kirk settles on "pi'neki'ne", which according to the footnotes, means "little shield-partner."
- Because I Said So: At one point, Kirk pulls this phrase out during an argument with Spock about his diet, "only belatedly realizing he was turning into his own mother."
- Bedmate Reveal: Kirk wakes up one morning to find kid!Spock in his bed. Unlike most cases, there are no hints of sexuality. Spock confesses that the temperature was too cold for him.
- Berserk Button: According to McCoy, one of the few things that can make Kirk lose control in front of crewmen is any threat to "their (currently fun-sized) Chief Science Officer and said science officer's precious dignity."
- Blunt Metaphors Trauma: Spock. After being told that he scared Kirk to death, he answers, "That is illogical, as you are neither dead nor capable of being frightened to that state by a being one-third your size."
- Continuity Nod: Events from the fanfic Insontis are referenced.
- Cuteness Equals Forgiveness: Kirk invokes this by holding up child!Spock when the admirals are scolding him about Spock's use of the technology."Besides, admirals," he added, scooping up the startled child, "how can you be annoyed with something this cute?"
- Cuteness Proximity: Spock discovers that the female members of the crew tend to coo over how cute he is. Even Kirk frequently wishes he could hug him.
- Creepy Child: McCoy finds it creepy for Spock not to display certain infantile behaviors like crying. He attributes it to his Vulcan heritage.
- Dangerous Forbidden Technique: Mind-melding becomes a dangerous thing with Spock regressed so far, but it doesn't prevent Kirk from trying it.
- Embarrassing Old Photo: McCoy takes a screenshot of Spock hugging Kirk, thinking that someday he's going to teach him about "the involuntary stimulus of cuteness."
- Exact Words: When the admirals call to complain about Spock using the Insontis technology, Kirk reminds them that they gave him carte blanche in his investigation.
- Fountain of Youth: the Insontis technology can regress a person as far as infancy, but the subject grows up faster than he/she would naturally.
- Half-Breed Discrimination: Kirk reflects on the bullying Spock went through as a child because of his human ancestry.
- Hates Baths: Spock doesn't like water, and one whole segment is devoted to Kirk talking him into taking a bath.
- High-Voltage Death: Narrowly averted. Kirk is nearly electrocuted by a faulty circuit, but Spock breaks the current Just in Time.
- I'm a Doctor, Not a Placeholder: After calming Spock following Kirk's accident, McCoy comments, "Glad that bucket of awkward is over...I'm a doctor, not a crisis counselor."
- Not So Stoic: When Kirk is almost electrocuted, Spock hides himself. Shortly after finding him, McCoy notices his hands are "clenched and trembling."
- Raise Him Right This Time: A smaller example than most. Kirk doesn't avoid the Vulcan training Spock went through the first time, but he hopes that, by being more accepting of Spock's humanity, he'll feel more relaxed.
- Sesquipedalian Loquaciousness: Spock sometimes speaks in big words in spite of his regressed state.
- Sequel Episode: The story follows up the fanfic Insontis, in which Kirk is age-regressed.
- Tastes Like Diabetes: An In-Universe example - adorable baby Spock makes McCoy want to throw up.
- Troubled Fetal Position: McCoy finds Spock in a corner with his face hidden behind his knees after Kirk's near-electrocution.
- Weirdness Magnet: McCoy reflects on the sheer amount of bizarre dilemmas that occur on the Enterprise after Kirk is almost electrocuted by a wire malfunction.
- You Didn't See That: At one point, as Kirk is chasing the pajama-clad Spock down the hall, he encounters Sulu and mutters for him not to say a word. Sulu responds, "Didn't see anything, sir."
