Jack came to you first, when he grew fond of the dark haired bleary eyed resident Mohan. He knew you'd been in a poly relationship before, more than him no doubt. He knew you werent exclusively gay - and neither was he.
nonetheless he was thrilled when he saw you the next day, in the ER frequently enough since you were a paramedic, trying to tease her and rile Samira up. It was your love language, your flirting.
and she seemed to fall for it. Hard. He could see it plain as day, as well as the conflict knowing you were already married. To Jack.
And then he asked. And she didn't even want the time to process - perhaps due to her being more of the open minded generation.
She seemed a little unsettled later that week when she came over for the first time. Samara ran her fingers across the marble counter, observing the kitchen, part of the old victoriana three story you and Jack shared in the outskirts of Pittsburgh.
Jack leant against the island, watching her, and you of course, but you were mostly busy with the routine you followed religiously - shoes off, feed the dog, beer, etc.
