Holmes waits a moment, taking in the sight of Watson in the tub, before he accepts the invitation and joins him. He's secretly a little pleased at being in this position, even if it means he can't peer over Watson. He settles back against his chest and sighs, leaning his head back against Watson's shoulder.

"The finest bath two dead men have ever shared," he murmurs in agreement, and he reaches a hand up to angle Watson down so Holmes can kiss him tenderly. He's still uncertain of their boundaries as far as sex goes, which is fine with him, really, even if he's already looking forward to when they might find that intimacy again.
