And now I can’t help but imagine:
WARNING - UNDERAGE DRINKING (OR THE VULCAN EQUIVALENT)
Years later, when Sybok is in university, Michael finds Sybok’s stash by accident while she’s trying to find a book she’s given to Sybok. Not knowing the effect it has on Vulcans, she decides that it’s her sibling duty to make it disappear as a last hurrah to teen shenanigans, and that it would be even greater to share it with Spock. Spock is around 15 at this point and is also unaware of the effect of chocolate on Vulcans because he doesn’t have an excellent relationship with his peers, so he accepts.
They sneak in Sybok’s room the next time he’s out and proceed to eat the whole stash. When Sybok returns he discovers them because Spock is so drunk he keeps giggling instead of running away. Michael is forced to reveal the truth to Sybok. At that point, it’s almost dinner time, and Sybok and Michael have to revert to 100% teenagers and
- invent excuses to Amanda and Sarek as to why Spock is not coming down for dinner
- actually prevent Spock from coming down to dinner, and generally sneaking out of his room to cause chaos.
They decide that it’s best to set up a constant watch. Dinner consists of the two of them, in turns, finding an excuse to leave the room to go check on Spock. The excuses vary from “I suddenly need to go to the restroom” to “I think I heard I-Chaya growl upstairs” or “I left the window open and it’s bad for my ongoing experiment.”
Amanda and Sarek are extremely suspicious of this sudden behaviour, but both Sybok and Michael are technically adults, so they raise their eyebrows and decide to let it go. Even though some crashes upstairs sound really suspicious... so Sarek stands up to go investigate.
Somehow, Sybok manages to convince Sarek that it was I-Chaya’s fault that all the vases on the upper floor were crashed. Through all of Sybok’s convpluted explanation, I-Chaya happily stays sitting in front of Spock’s door. If he had a tail, it would be wagging. Sarek finds himself deeply unconvinced, but still decides to give them the benefit of the doubt, so he returns downstairs. Behind Spock’s door, Michael is desperately trying to keep Spock silent so they won’t be discovered.
The next morning, Spock wakes up with the mother of all headaches. Also, all siblings have learned their lesson about chocolate, and none is brought into the house ever again.
(They never find out about Sarek’s stash. Sarek hides it better than Sybok)
