I’ve spoken quite a bit about Katherine and Elijah smut with summersbrine. Basically Katherine enjoys finding ways to get under his skin at improper occasions.
Having a dinner party with important vampire for territory negotiations? Katherine will play footie under the table. Elijah generally keeps his cool. Until they get to the bedroom, which is Katherine’s true goal, though she gloats when she can get him flustered.
jesus christ this is so late sorrY SORRY
Elijah, she finds, has a certain distaste for the States that is quintessentially European with a fundamental root in the apathy of immortality.
Elijah, she finds, also likes physics.
They are at a science conference in Geneva when it happens, for the first time. She is atrociously bored, eyes almost rolling to the back of her head and she is on her fourth martini when he makes his way over to the bar, and orders their most expensive Scotch in a low voice.
"I’m bored." She says, and leans closer to see if she can break that extraordinary control. "I want to leave."
"Well, unfortunately, Katerina, I wish to stay." His lips quirk slightly, so fast that she could have missed it, if she missed anything. "And so long as I wish to hold your life in my hands…"
His voice trails off suggestively. It’s not the kind of suggestion that Katherine is used to, and she blows her breath out slowly.
"Stop calling me that."
"Katerina?" He sips the Scotch. She takes a guess, from the minute pursing of his lips, that it is at least a decade younger and a few grades below what he’s used to. "But that’s your name."
"That was one of my names. I have a dozen others that you can use. Maybe I should run them through for you. Or maybe we should be done with names altogether - "
"Doctor Retzius," Elijah cuts through her offer easily. God. It wouldn’t be a chore by any means, but she needs to get out of here before she stakes herself. She needs to slip him the first chance she got, she needs to make sure he won’t hand her over to Klaus at the first notice, she needs to, she needs to - "I enjoyed your presentation very much."
Katherine sees her chance, and pounces.
"Katherine Mikaelson." She offers her hand and smiles at the little grey doctor; hears his heart jump. If he keels over right now it would be very awkward. “My husband here assured me that your presentation would be far more enjoyable than a honeymoon in the Bahamas, and for once he’s right. A pleasure.”
"A honeymoon?" The doctor turns to Elijah; dare she say it - is that a blush in his dead cheeks? "Elijah, you abominable wretch! You forced your lovely wife here for your honeymoon?”
"I am forever suffering at his hands." Katherine bats her eyelashes, lays it on thick before Elijah has a chance to reply. "He’s lucky I’m so in love, else - "
She presses a kiss to his cheek. Around her waist, his hand snakes, and he sinks his nails into her hip.
"Will you excuse us?" Elijah says abruptly, without his usual smoothness, and whisks her away. When they stop, in some dark corner of the hall, the twitch of his mouth could almost be anger.
She’s seen that before. She’s seen that twitch, that minute click behind the eyes, the crack in the perfect veneer; the calm before the storm. That final decision before the sudden rush of blood. She feels a tingle run down her spine.
"You’re acting out." He says.
She tilts her head. “You want the alternative story to be how you came here with an unattached woman? Elijah, what about my reputation?”
Her fingers are tip-toeing up the arm of that Savile Row suit. He catches it sharply. “You are here so I may keep an eye on you - “
" - so you can hand me over to Klaus like chattel, you mean - “
" - so I may do with you as I like.” The emphasis is clear. Katherine met Machiavelli once. She knows how this game is dictated. “You want me to have every reason to spare your life when the time comes for me to choose.”
She blinks slowly at him, eyes half-lidded. And smiles.
"You already will." She says, and tears her hand from his.
