He didn't mind the touch - he had learned that, like Thor, Ruby was expressive in that manner, though a good deal less firm - and he simply smiled at her. She gave compliments aplenty, herself, and he wondered how many she got in return. Loki was a good flatterer when he wanted to be, charming to a fault, but usually only when he wanted something from someone, and he found upsetting them would make his life difficult. With Ruby he wanted nothing, and thus his compliments were sparse - but at least they were honest.

"Well," he said, "I know the base structures for several languages, and many of them split off and built from that original, so when you know one you end up knowing about five more, if you can wrap your head around it enough. So I don't know how to quantify it. I was simply translating, though. It keeps my thoughts active."
