[Momo's always been skilled at reading body language, so he picks that look in her eyes that contrasts the casual manner. Nonetheless, he continues casually enough himself, since he didn't come to judge so much as offer an alternative that didn't involve having to thieve something and potentially hurt relations early on.]

Nah, they're really simple to do. The problem is gonna be that this place doesn't really have a filing system, so there's as much chance that whatever you've got there is going to be scrolls on wormipede husbandry or a fantasy book as history. I'm looking for historical scrolls too, and Cwyld stuff is always gonna be handy, so if we both look and I translate then there's a chance we'll find something that's useful to both of us.

[Appealing to the practical side - two people searching is faster than one, and if he translates then they can know immediately whether what they get is useful as opposed to Daenerys having to take something away and potentially find out later that it's useless.]
