He always delights in watching people as they experience firsts. This was a minor thing and, gods' knew, Yennefer had known more impressive firsts than a bit of mechanical water pumping, but it was still a first. He watches her face as she balks at the idea of a cold bath, then her surprise as the near boiling water pours out of the swan's open mouth. (Why that design, he was truly flummoxed about, but apparently there were worse ones. The horse head faucets were supposedly very alarming.)

Her laugh brightens his smile and he leans to drag his fingertips in the excruciating heat of the pooled water as she twists the cold tap open as well. She looks at the pair and then back at him.

"That is all," Jaskier confirms. "I heard one mason chatting about building something faster, yesterday. He said something about a stall, but I can't imagine why someone would want to rush a bath."

The sound of the water filling the tub is a calming, monotonous, droning sound and Jaskier sighs delightedly. It was the sound of his not having to fill buckets. Glorious.

"Thank you, by the way," he says and has the decency to look a bit chagrined. "For coming to this. For helping with Valdo and, well, everything. I don't tell anyone that I appreciate them enough and you deserve it more than most."
