The sight of Horatio seeking the gentle affections earns a bright smile. The thumb twisting to smooth at his fingers is entirely welcome. Archie shifts his grip to take Horatio's hand lightly, brushing a light kiss against the inside other young man's wrist.

It's then he catches William's startled glance, and he manages a soft smile as he rests his cheek briefly in Horatio's palm, nodding encouragingly.

He'll get up in a minute to properly hold them both. For now, he has to just marvel quietly at the sight of the two men who hold his heart holding one another. For now, he has to press another kiss against Horatio's skin.

"Thank you," he murmurs softly.

It's absolutely for the both of them.
