Sulu reached up and flushed the toilet, leaning back slowly so that he wouldn't slip and fall - or, more likely, black out from the vertigo and fall. He kept his eyes closed, barely opening them when he felt the glass being pressed into his hand, and then felt Ianto's hand against his head again. He did exactly what Ianto said, sipping at the water slowly. "Uugh."

He hated feeling covered in blood; he also hated being stuck in a towel, that he was concussed, that a ghost was terrorizing them on their damn vacation and that it had taken a weird liking to Ianto, one that Sulu did not appreciate. He wondered why he was focusing so much on that aspect, and why he was taking it so damned personally, but he decided that now probably wasn't the time to question himself.

"I'm - I'm sorry," he said after a few minutes, hoarse but not quite so slurred now. "I didn't mean..." To ruin what had been a relatively okay vacation? Yeah, right. "...I-If you hand me a towel, I can... I can clean myself up. We can... think of a way out of this."
