Out of Character: : Davik is only unconscious for a minute or two. And, as stated above, he gets back half of his HP within about an hour. John-Louis does not provide you with any resources, healing or otherwise.
You do notice, however, that he puts his winnings inside a chest that he keeps next to his chair. You can see when he opens it that it is full of gold pieces. Several thousand, by your estimation.
Before following the group Ardo turns to John-Louis. "John-Louis are we free to roam the mansion to find someone who knows about the mist that is outside or can you call someone to us that call help us get past this mist?"
John-Louis gets a distant look in his eye as he responds to Ardo, "Are any of us really free? I mean, look at all of these mortal trappings. We must abide by the limits that the physical world puts on us." Then, seemingly coming back to the conversation and realizing that he's getting odd looks from the party he quickly adds, "But, you mean can you explore the rest of the house? Well, I for one do not care but I suppose I can't speak for everybody."
"Okay thanks for that information John-Louis, maybe after some rest my friends might come back for a rematch? If we run into anyone that seems hostile can we tell them that we are friends of yours just looking for a way out?"
John-Louis bows graciously to Ardo. "Please come back as often as you like. There's nothing I like more than a good boxing match! It helps to pass the time.
"As for anybody that you meet, you can tell them anything you like. But, I'm curious, what makes you think that proclaiming to be a friend of mine will help you in anyway?"
"Well as we are not thieves or trying to kill anyone just a group of lost people wanting to find a way past this mist, I do not want to get into any fights that could be avoided. Sometimes having a friendly person like yourself that can vouch we are just trying to leave might stop a situation from becoming violent. I do prefer fun fist a cuffs over violent misunderstandings."
