Right, I'm off to bed. You may notice in the Narrative, you can see the actions of Harold the Innkeeper of the Unicorn, but you did not hear the conversation. I will do this to keep those not near enough or in the conversation out of it ...
In this case, it will be up to Tal to tell the others what she found out, if anything from Harold.
You may also see this between NPC's, and unless you tell me you are "eavesdropping" or moving to a closer table, you may see actions or interactions between them, but you may not hear them (well, until they get agressive and start yelling at each other possibly)
