Judging from how he looks and smiles to Lynda, and their general dynamic, I suspect there is little of him that Lynda Stark doesn't know. Of course, Brooder being brooder, surely there is still something, but I doubt it's something that Savunn could know but not her.
So my bets are that either he knows that Dandy-Lion is here, wants him to show up but know he is more confortable with as little people as possible or is Riveteer, not Lynda, who has some work to do.
Kether--Exactly right about the Brooder/Riveter dynamic. As for secrets . . . Adam also knows, regardless of how much he trusts someone, there are some secrets that are not his to tell.
