"Thanks~" His grin is cheerful, even if it's not as wide or bright as he meant it to be, and Esteban gets a little confused at the open support that he gets, surprised that the stranger would go that far for him. He's not unsteady, but he is slow, and his reaction time is longer than he would like, so his companion's help is appreciated. Please don't ask about why he's so warm though, Wash. The half-elf doesn't have the braincells to explain it simply.

"Where'd'you get the blanket?" His thoughts are too blurred to make much more of a conversation, and he's a bit surprised at that, wondering if there might be a storage area nearby that people can just grab blankets from. They should grow some patches of grass in the carriage? Maybe? Oh, but the snow and inconsistent weather might make that a hard challenge. He gives up the half-formed idea, at least for now.
