Certainty bubbles through him. It doesn't quite stay stuck to his ribs, but it rushes around his heart pleasantly for a few moments.

The sensation is strong enough at least as the other men's lips meet. The surge of joy prompts Horatio to lean slightly forward, aiming to peck against William's cheek.

Three bodies moving together isn't quite as easy as two, of course. Maybe no one will mind that Horatio misses and winds up nipping slightly under William's jaw instead.
