Arthur's sword clatters to the stone floor of the cave.
"Merlin, what—" He's tired, exhaustion showing in the way he holds his shoulders, in the dark circles under his eyes, but that doesn't stop Merlin from snaking a hand up to the back of his neck and pulling him down. He nuzzles the soft space just below Arthur's ear, drags his lips along Arthur's rough jaw. When he captures Arthur's lips with his own, Arthur sags against him, and Merlin steps back to support him, leaning against the cool stone. There are great claw marks in it, but the beast won't hurt them.
"Thought you— I— You came for me." Merlin looks so earnestly touched, and Arthur ravishes his mouth until they're both panting hard.

Quickly, he placed the figurines back in the carefully carved replica of Camelot Castle (he was quite proud of the way the Great Hall had come out), nearly forgetting to pick up the Arthur doll's tiny sword, which had been forgotten on the floor of the Cave of Doom set. Everything replaced, he puffed up his chest importantly and prepared to make his usual grand entrance.
…And if the boy asked what took him so long, he decided he would say something about the way the Moon could not shine without the Sun. That should keep him occupied for a while.
