Ianto smiled softly, stroking Sulu's cheek again before leaning forward and kissing him gently. It was sweet, how Sulu acted when he was this tired. Granted, Ianto was still a little worried about him, worried about his health and things like that, but Sulu said he was fine, and so he believed him (mostly). Pulling back from the kiss, he slowly eased Sulu off of his lap to sit in the sand instead. "I'll be right back," he said, standing up and carefully making his way back across to the field to pick up their clothes and Sulu's kit, as well as a sample of the flower like he'd promised he would.
