But there are two earlier instances where Christianne uses the Fictionary. I'll put them here; the second one I think I might actually need something to wave it at for her to get the info.
“No, don’t!”
Eledhwen raised an eyebrow. “Why not?” she demanded.
“Chocolate’s intoxicating to Vulcans!”
Eledhwen paused. “Really?” she asked, the Bleepolate halfway to her mouth.
“I’m pretty sure I read it somewhere,” began Christianne, before pulling out something that looked like a PADD and putting what looked like a Game Boy cartridge into it. She aimed the device at Eledhwen. There were a couple beeping noises and a puff of smoke, and Christianne emerged from said smoke with a couple coughs, a grimace, and an answer. “However, the Fictionary informs me that in an episode of Deep Space Nine this barkeep dude named Quark offered chocolate and Vulcan port to some Vulcan who dropped by his bar. Port’s a sweet sort of wine, so I’m guessing Vulcan port has a lot more sugar than other sorts of alcohol, which would explain why Vulcans are immune to alcohol, but not to – what?” She scowled at Eledhwen, who was grinning at her.
“If this makes me inebriated, and the fic is purported to be as bad as you seem to think, then do you not find it logical that I should face it in a better state of mind?” the elleth-turned-Vulcan asked with amusement in her eyes as she popped a piece of Bleepolate into her mouth.
And the second scene:
In the Words, Pike gave Spock permission to court Seraphina.
[...]
As they watched, Spock exited the office to go teach his next class. Christianne pursed her lips and spoke up again.
“Anyway, before I got distracted by soppy romanticised abuse,” she said, with a small shudder that Eledhwen frowned at, “I was going to say that I thought it was the CMO that approved interpsecies relationships.”
“Really?” wondered Eledhwen. “Where does it state that?”
“I...” Christianne paused, fumbled for the Fictionary-disguised-as-PADD again, and inputted something again. There was a buzzing noise; Christianne growled, before removing a cartridge and replacing it with another. “Aha. Here it is. Starfleet Handbook of Personal Relationships. He’s gotta clear this with a medical officer before he goes boinking someone who isn’t his species. Or only half of his species. Admittedly, from what the Fictionary tells me this was only mentioned in the Voyager era, so that might not be a thing.”
“Still a logical precaution, though,” Eledhwen pointed out. “Remember when we first made our relationship known?”
“Nurse Hearth had us in for The Talk. I had never been more uncomfortable in my life,” agreed Christianne drily.
And for the bit you saw, I can have her complain about DoSAT not making the Fictionary more streamlined and like a wiki instead of just a CAD with extra snark. Because I'm under the impression that Christianne is a fairly spoiled Agent in terms of tech, and would rather just have a smartphone device where all her tech are apps.
(that sounds interesting and would probably lead to Issues in the PPC amongst the older generation of Agents.)
