Dr. Midlin started her assessment by making an official recommendation to Starfleet Medical that Lieutenant Uhura remove herself from Commander Spock's quarters so as not to detract from the intense treatments necessary to, in Midlin's words, "assist the Commander in getting in touch with his feelings." Uhura had the good sense to blow up in McCoy's office at the hospital and not all over Midlin. McCoy finagled a favor out of M'Benga who let Uhura crash at his empty San Francisco apartment.
Dr. Midlin's next report indicated that Spock was suffering transference - burying himself in work to avoid dealing with his traumas. Dr. Midlin prescribed more fun in Spock's life and assigned herself as his fun therapist. McCoy performed his own investigation using the most sophisticated diagnostic tool he had for Spock - his bond mate, Nyota Uhura. Uhura determined, through their telepathic link, that any unresolved trauma in Spock's life originated from Dr. Midlin. Uhura described - for Spock's medical record - Spock's daily struggle with the incompetent, insensitive woman and Midlin's daily disruption of Spock's control, as communicated through their telepathic bond. Thanks to Midlin's perpetual presence in his apartment, Spock's life now provided no opportunity for intimate relations with his bond mate. Uhura's increasing frustration with that sacrifice assaulted McCoy's ears loud and clear. Thus in addition to hours spent daily getting into Spock's head, Midlin spent hours getting under Spock's skin every evening - all without Uhura's presence.
Midlin stalked Uhura's mate.
Every day spent in Midlin's presence escalated Spock's discomfort. What concerned McCoy more was Uhura's observation that after each "therapy" evening, Spock's thinking became more and more befuddled and confused. Concerned that Spock might be drugged, McCoy and Uhura devised a plan: McCoy would drop in at these "recreational therapy" sessions to check on Spock. They would compare notes later at M'Benga's. By the third surveillance mission McCoy suspected something weird was indeed happening to Spock but he couldn't figure out what, when or how. Blood tests taken before Midlin's morning arrival at Spock's apartment yielded no known psychotropic drugs in his system.
Every evening McCoy arrived at M'Benga's apartment no wiser than he'd been before. He and Uhura talked through his frustration and mounting concern. Uhura's patience ran out; McCoy's next visit would be his last without her.
"Look, Uhura, whatever it is, it's subtle. I don't doubt Midlin's doing somethin' to him but I can't catch her at it."
Running her hands through her loose hair, Uhura paced to stimulate her thinking. Taking a page from Spock's book, she asked McCoy to describe everything he'd seen and heard.
"I showed up at Clancy's Bar again and they were sittin' in a booth. Spock looked like he was sittin' in the next booth over; they couldn't have been further apart. Midlin had this formal Vulcan robe thing on so all I saw were her hands and face. Lots of makeup. Had her hair up too. Gave me the shakes lookin' at her. Looked like she was drinkin' a Cardassian Sunrise and actin' like it wasn't her first. Spock had a cup of coffee -"
"Not tea?" Uhura interrupted.
"Looked like coffee to me. Midlin was doin' some serious flirtin' but Spock kept outta her reach. He drank his coffee and sat there while she drank her cocktail."
"Who ordered the drinks?" Uhura suddenly asked.
"I dunno. They had'em when I got there. Why?"
"A hunch. Meet me here tomorrow at 16:30."
"You gonna tell me what we're up to?"
"Not until I'm sure. Dress up nicely."
"I've got more sense than to get in your way when it comes to that green-blooded elf. See you tomorrow."
