"In... Dia.." He would nod, seeming to understand that concept. "Oh, like the Dark Pointy Ear People!" Also known as the Drow, or Dark Elves. Dean knew of them. But, he didn't really like the ones he had met before, they were mean to Dean! Given that, Dean generally took people on a case by case basis. Some were mean, most were nice. And Ritchie was deemed nice.
"Thank you! Dean likes these clothes." Though, he was use to wearing much less than this, armor never suited him that much. He wouldn't understand what Ritchie meant by contagious anyway, and it wouldn't really matter to him. Dean nodded when he was asked to put Ritchie down, which he did, very gently. He may have seemed like a big, dumb brute, which he was, he was also very kind and gentle. Unless angered.
Dean thought on what Ritchie had said for a moment or two. "Oh, Okay! So.. Ritchie liked this Indian person! Is sleeping with someone.. Is that.. Is that like mating?" His head tilted to the side once more.
"Would.... Ritchie.." He was doing his best to remember his name. "Like to join Dean in some spicy water? Fiery Haired Lady showed it to Dean not long ago, Dean likes it a lot." He of course was speaking of alcohol, mostly vodka or rum. His tail wagged a little bit, being excited to (hopefully) make a new friend.
