Given that Admiral Rudolph Sidwell is now in the vicinity and spending time in both Nott and around the Castle, Thancred would be curious to learn more about him. However, rather than going for a direct approach, he would prefer to be covert about it. This would mean, if possible, tailing him around (within reason / to places he could feasibly access), potentially eavesdropping on his men wherever they're hanging out to hear the sorts of things they might say about him when he's not around to hear it, that sort of thing.

Just curious what he might learn!
