Chapter XII - Even if you are not yourself
The last couple of days were definitely shaken at the house of Sarek. For starters, Spock hadn't slept since the day he called Jim's name. He had spoken nothing else since that day, but now it was obvious that there was a consciousness inhabiting that body. When someone entered the room, he always turned his head to identify the individual, and when someone was caring for him in any way, he kept his attention solely on that person. It might seem insignificant, but it was a tremendous evolution after two months without any improvement. What was about to prove to Sarek that Vulcan could actually suffer from stress, however, was something else. Part of Spock's memories seemed to have returned, but the way he acted indicated that his brain didn't know what to do with the large flow of information that it had received in a short period of time, and the way it chose to deal with it was about to lead Sarek to absolute madness. Using markers, pens, brushes and other materials Amanda had because she enjoyed working with real paper rather than electronic, he began writing on every available surface. Kirk still haven't been able to wash the trans-warp beaming formula of his arm; Sarek had to have the main living room painted to remove the complete stories of Sherlock Holmes; Uhura lost a day's work when Spock drew the molecules of every single hormone that was released during pon farr in the papers she was using to take translation notes, but the most impressive was that was on Spock's bedroom walls. Sarek brought physicists to copy the formulas and check the results of what appeared to be a brilliant and novel solution to a chronic energy waste problem of newer Vulcan ships.
It was as if Spock had turned from one moment to the next from an uncommunicative autistic or perhaps a person in a catatonic state into a savant. No one could explain how it was possible, though whole teams of doctors and priests are looking for answers since that afternoon.
Finally, after a particularly strong migraine, when Spock started writing all of Mozart's music in the kitchen walls, Kirk decided to seek help. Whatever was happening to his brain seemed to be connected with the moments when Spock was more lucid. None of the Vulcan doctors knew how to explain the connection, but it seemed obvious that it existed. Spock's recovery should be connected with Kirk's symptoms somehow, and while they didn't know in which way, it wouldn't be possible to rule out the possibility that Spock was damaging Kirk's brain. He had to admit that the pains were getting stronger, as if his brain was being pulled and torn, but it seemed such a small price to pay for improving Spock's health that he didn't care too much about it.
However, the suffering that he had now was even greater than before. After the initial enthusiasm, to see Spock moving and performing various tasks, but without acting like himself was too weird. Because the Spock that had drawn diagrams of Enterprise perfectly in the sand of Amanda's garden wasn't exactly his Spock.
