The way I envision it, Rellek responds to my gestures with a quick set of his own, to show his amendment to my plan: climbing over the building to really get behind the guys. Therefore, we see Rellek and Karis disappear down the alley away from our view and wait several moments to (hopefully) give them enough time to scale the wall, belly-crawl to the other end of the building, and begin preparations to climb down into the quad once we draw the 2 (from our perspective) guards our way.
After several minutes, we will continue moving down the street into town slowly, but not entirely stealth-like (we want them to hear us, but look like we're sneaking). Ideally, I would like to make it at least halfway between the quad and the alleyway Rellek and Karis hid (no closer than 6 squares east of the closest guard, but not stopping before 9 squares to his east, unless he sees us earlier and tells us to stop).
As to the smack talk, I agree with the ranged attacks, but I would like to give the guards a chance to tell us a little bit about why they're here (to attack us, take Mardrick or keep us outside of the house, etc) before we drop into combat. To that end, being that Mardrick is an NPC, would NT rather I do the talking? I only suggested Mardrick because he is, after all, the one they're after; thought it might be punchier coming from him.
