For Jude (genedriver) and Doug (mansome), you've got full permission to jump in! Considering Jude comes from a setting where the best info is gathered at places like pubs, Jude might actually appreciate any input Barkeep has to offer (if it's helpful). With Doug, his reaction will depend on what's happening at the moment.

As for Nel (divinewrath), I'd appreciate a PM first beforehand. She's very cautious and will not appreciate eavesdroppers much if she catches onto them.
