Something in his brain record scratch stops at the kiss to his finger. It's so simple. Simple gestures never go so far with Jim. Except he's just staring at Sherrinford now and opens his mouth. A fly could probably slip in there if he keeps it up.
He was supposed to be the one teasing him with the outfit and the glasses and reminiscing. A blink and Jim wants to ask how it backfires so badly, but doesn't. Then Sherr would know his brain is going seventy five kilometers a second over it.
The staring and silence keeps for too long. Jim finally swallows hard and nods, patting his cheek and swiftly turning around.
