Ah -- [He looks away, but he can't really expect her to stay in wet clothes, so no protest.] It's fine. You need to dry off.
[He makes himself useful over at the fire pit, where a quick fireball spell makes quick work of the tinder.] That should warm the place up.
[Part of him very much wants to glance back at her, but he dare not. So he glances around, his eyes falling on a small chest which he approaches hopefully. Inside are some beach towels, not exactly blankets but at least they're clean and dry.]
[He plucks two out of the chest and holds one up for her -- making sure it's blocking his vision.] Here, catch.
[With a mental shrug, he sheds his own uselessly drenched shirt and hangs the other towel over his shoulders.]
