Encouraged, Merlin's smile widens and becomes more devious still, "Oh, definitely." He doesn't wait for the girl to challenge him further. Instead he uncaps the Sharpie, glances around to confirm that they aren't being observed, and leans forward to begin writing something on the edge of the bench between her sneaker and his bruised knee.

It doesn't take long and when he straightens, the characters become visible: MP+IR. He looks at her defiantly, expecting her to push him off the bench or make a face or just make fun of him. If she goes for the Sharpie, though, he's definitely turning that + into a ♥. Do your worst, Imogen.
