He didn't really know. He was just observant. He'd seen what the cats had sitting around at the cafe and had gone from there. And the brush was common sense. He didn't want hair all over his apartment.
"It's fine," he said, waving off the thanks. He didn't need it. Didn't really want it or know what to do with it -- because, well. He owed her a lot more than some fucking cat toys. He owed her everything, and it wasn't the sort of debt that could be paid off with money.
"Isabel," Levi offered her a level sort of expression before nodding in the direction of the registers and cashiers. Frankly, he hated this part. They all made this ridiculous small talk that he wasn't interested in. Whether or not he'd had a good day was his own business, and if he hadn't found everything okay, he probably would have asked for assistance wouldn't he?
Well, no, he probably wouldn't, actually. But he wasn't about to start shit when he was ready to pay, either.
Luckily, he used Isabel as a bit of a distraction from having to talk -- this was a learning experience for her, after all, and so having her front and center only made sense. He handed over the cash when he needed to though.
