Loki just smiled at Granny - not in an infuriating way, more in a way that he understood her, or at least why she was doing what she did. If Ruby was all Granny had, he could understand a little protectiveness. In any case, in some suspicions she was probably quite right - Loki did represent a wide, wild world for Ruby to run off into. Granny just clearly didn't understand she had already done so.

When Ruby came back, he was looking at the napkins under his cup in bemusement. "Has she?" he asked, not bothering to turn and catch a glance - he'd see what she looked like soon enough, of course. He was curious, though, because after meeting Ruby's grandmother, he wanted to see if there was anything he might glean from someone else in the town, about how natural or supernatural they might seem. "Oh, don't worry about your grandmother. She's quite solid, I suppose."
