She follows his direction to head inside, relieved to be able to step out from under the umbrella into at least a relatively dry place. The occasional bucket of water catching the toxic water scattered throughout the little shop bringing back quite a few memories from her youth. As much as she's confident she could survive in the down, she already was missing the warmth and security of the Phantomhive estate.

"I'm sorry... it just really, really itches." Her voice clearly displays her discomfort. "I appreciate ye taking care of me, Sebastian... I'll find a way to get a job and pay you back right away!" Being tacked onto her tab at home would be far too much. She already accepted that the stingy demon had every plate and cup memorized, even now. Possibly even ones that hadn't even been dropped by her yet.
