[X] Start with Stone Hedge and the Brackens, perhaps trying to fit in a private meeting with Lady Catelyn (not words you thought you'd be thinking, albeit it is a different context) before meeting her father. The fact of the matter is you have made some gains with making your view of the Faith seem favorable, and religion is a prickly point with Lord Bracken if by nothing other than the sheer dint of his House's relationship with House Blackwood, and you have multiple ties and methods to get a favorable meeting at first blush with Lord Blackwood, through the auspices of Uncle Brynden and through your obvious championing of his Gods, to simple if distant blood ties. -[X] Furthermore the Brackens form the base of the knot in this case even if it seems possible a Blackwood might either untangle it or set the whole thing alight. You feel reasonably confident you can get them to set aside open conflict when you present all the other various threats facing the Riverlands and the Seven Kingdoms at large, and you have a reputation as a fair dealer and honorer of oaths. There's not really a whole lot more you can do to make a better impression, but a whole lot to make a worse one.
