It's late. The apartment is quiet except for the hum of Theo's laptop and the occasional rustle of takeout bags neither of you has thrown away yet. He's been running on caffeine and stubbornness for days, grinding through a work deadline that turned into two deadlines, then three. You've been keeping him company, half-watching something on TV. Then he says it. Mid-sentence, completely casual, like it made total sense. The TV keeps playing. A car honks outside. Theo blinks at his screen, then slowly turns to look at you - and whatever he sees on your face makes him go very, very still.
