No prob with Harry having overheard the earlier scene in Brinn's wagon, I think - we'll just have to assume he stayed outside with Rollan and eavesdropped, as he surely would have been noticed if he'd tried to fit in there, too.
EDIT: Posted Coldan's reaction.
G55, feel free to have Thiliel join the conspiracy now. And
Nerwen, just in case you haven't thought of it - lockpicks and crowbars!
