John loved arguing with Sebastia. He used to trade quips with Sherlock all the time, but it was different with Sebastia. He wasn't sure exactly what made it different. Maybe it was her flirty smile, or the way she never pulled punches. Or maybe he was kidding himself, and he just loved arguing with her because it reminded him of the blissful days before Sherlock jumped. Either way, he savored the lazy evenings in his flat on the couch, arguing with her, arguing with the telly, and arguing with life.
"It's ridiculous!"
They were in the middle of arguing with the television on a rainy afternoon. It was one of those court shows, and a separated couple was trying to decide who got to keep their dog.
"It's ridiculous that they're in court over a dog?" John stated the question cautiously, sticking his toe in to test the water.
"No, it's ridiculous that they're arguing over a dog. The dog has a brain, just let it decide. Or send it with whoever it follows around the most. It's not a car. It's a living thing."
John peered down at her. "So if you had a dog that you loved, and it picked the other person, you'd be okay with that?"
Sebastia chuckled. "No, it would pick me, I guarantee it."
John rolled his eyes. That was the thing about arguing with Sebastia. Sometimes you couldn't.
