"Water? Ah..." Huh. That probably would have been a good idea. Lucy-chan looks like she's dying for a drink, and that might be more literal than Musashi likes. She looks out to the end of the alley to the busy street outside. "Wait here a second." And like that, she's just gone, there one second, and then simply not, save for a small breeze that signifies how fast she must have taken off.

Distantly Lucy might hear someone cry "Hey, what the f—" and Musashi offering a quick thank you before the samurai Servant is back at her side, with a water bottle in her hand.

"Good thing it's a hot day, ne?" She asks, unscrewing the cap. "Lots of people were smarter than we were. Here, easy does it." She holds it up to Lucy's lips, tipping it forward so she can drink a little. Probably the less she moves the better right now.
