Bart's insight check: 17 

You thank your lucky stars that you remember to grab everything before you jumped out of the wagon.  Finding a suitable group of bushes, you settle into your disguise, confident that you have it all set correctly.  Now it is just a matter of waiting.  Have you ever noticed just how maddening it is to wait when you can't see what is going on around you?  And only the occasional sound to indicate whether danger is lurking nearby or moving further afield?  Time seems to stand still, often even threatening to move in reverse for what seems to be an eternity when only a few seconds have gone by ... .  Just as it seems madness is your only option, you hear a voice, not too far off, calling "I know he headed off this way, why don't you get your arse down here and help look!"  Footsteps and rustling from, you guess, 20' away.  Then a booming voice, seemingly right in your ear, "You wanna come over here and say that again?"  The footsteps recede, moving away from you, and unless you are mistaken, further away from the wagon as well.

Kina makes her way down to the farmhouse, clopping down the road, surprised at the loudness of her own hoof falls. In the still air, she sounds like a full blooded warhorse. Coming to a stop in front of whatever farmhouse has a stable, which will be sufficient cover for her to sleep in, she cups her hands over her mouth to call out to its inhabitants.

"Hello in there!" she calls out. "Hate to bother you at this hour, but do you mind speaking to a traveler?"

She keeps a respectful distance from the farm house. No reason to scare the folks inside by knocking on their door without warning.

Still hiding in the bushes and approaching with caution (stealth) to get within 30 ft of the oxen pulling the cart and will use mage hand to slap their behind making them rampage away, possibly pulling the cart far away. Stealth check 20

After a moment, the door on one of the houses opens.  <<Roll a perception check as well.>>  A man in his mid-thirties, you guess, steps outside and calls over, "Good evening, milad....dee," his voice cuts short and his jaw drops.  In but a moment he recovers, "Pardon me, and my staring, but never seen one of your ilke before.  You can call me Arn, how can I be of assistance?"  He stops a few feet away as he concludes, arms out from his sides and gives a slight bow.

Arn looks up from the fire, and taps out his pipe as he rises.  "We don't get a lot of news in these parts.  Weekly crop and supply wagons, taking away our surplus and bringing in what we need, the occasional traveler, and periodic prisoner transfer up to the dwarven mines.  Plenty of gossip, but not much news."  He looks like he may say something more when a voice calls from outside, and he heads for the door to see what is happening.

OOC:  Semi-literate would be the best assessment.  Not a lot of book learning, but life is generally easy, so they have time for education.

As you come back within sight of the wagon, you see (you assume) the driver standing up on the seat, craning his neck trying in an attempt to catch your movement and locate you.   Timing your movements for when he is looking in another direction, you manage to get in rang and softly cast your cantrip.  Not exactly the slap you were looking for, the ox nonetheless starts moving, jerking the cart.  The driver, caught off guard, loses his footing, and tumbles into the bed of the wagon.  However, with the wagon brake still set, the ox stops pulling after only a few steps.

Other than windows, nothing presents itself as an easy exit.  Roll a Perception check.

Kina bows in kind, but in the manner she was taught, which might look a little odd to him.

"Good eve, mister Arn. It's quite all right. I suspect you've heard stories of my kind thundering by in huge herds on migrations, but I assure you, I'm alone. My name is Kina, and have traveled from the Shire on my way to Moorsedge, but I could use a place to sleep for the night that's a little warmer than a rock bed. I have coin to make it worth your while, if you have room in your stable for another half a horse." she says with self-effacing humor.

"Errr, that wasn't really a joke, though. A stable is all I require to be comfortable for the night."

(Perception: 10

Bart makes his first attack on the one that has fallen by charging with his rapier and driving the sword into the mans back: Attack role w/ advantage 16 ; Damage 3. and then uses his bonus action to attack with his dagger: Attack role 7 ; Damage 5

Before Arn stepped outside, you caught glimpses of shadows peeping from the windows of a couple of other houses, even though their doors remain closed.  Arn replies, "certainly, there's an empty stall in the barn you are more than welcome to, although the straw in it hasn't been changed very recently."  He stammers a bit at this point, "uh, um, uh, that is what you were asking, yes?  Pardon my ignorance on your sleeping needs."  A female voice calls from the open doorway, "and don't forget to see what she wants to eat!  Fewer leftovers to put away."  Glancing up at the voice, you see a woman, you presume the man's wife, leaning against the doorframe, a small smile on her lips at the man's discomfort.

Your rapier strikes, eliciting a yelp of pain from the man as he rolls away from the slash of your dagger and comes to his feet in the bed of the wagon as he draws against you.  Fortunately for you, his roll carried him out of reach.  You notice a cut above his right eye, rapidly swelling.  He must have fallen hard to get a shiner like that, you muse.

Bart takes another two stabs at the man. Rapier: attack role 15 ; Damage 9 . Dagger: attack role 9 ; Damage 4

You are quite sure there is not a back door, and there seems to be only one new voice outside, female at that.  Bethann leans against the open doorway as you hear Arn stammering over something.  Bethann calls out, "and don't forget to see what she wants to eat!  Fewer leftovers to put away."  She looks over her shoulder at you, "don't worry, Sir Wil, we still have plenty of food if you have the appetite," and gives you a friendly wink, before turning back towards her husband and the visitor(s).

As you gain footing in the bed of the wagon, the man tries to feint away from away from your rapier, but not well enough, and only to move straight into the path of your dagger.  As the short blade sinks in, his eyes go wide, and a dark red trickle rolls from the corner of his mouth as he collapses onto you.

Bart uses his action to dodge the on coming corpse (dex check just in case 5). after the corpse is on the wagon Bart painstakingly cleans his feather of any blood. Looks for anything useful or valuable he can take (perception check 8) and leaves running to where the nearest city would be in his best guess.

You essentially fend off and avoid the falling corpse, however cleanup will take a little time.  "Looks like I hit an artery, this stuff is everywhere," you think.  Finally finishing up, you hear a voice calling from still a distance off, "still no sign of him....hey, wha, you taking a nap or something?"

Kina laughs in a good-natured way.

"It's quite alright. If there is clean straw, I'll clean it up and make my own bed, so to speak. The only other thing I need is a pillow, really, to lean against. I completely understand feeling awkward. I find myself being quite nervous around human homes, in fact. I'm always afraid I'll back into something or fall through the floor, bang my head on the ceiling, and don't even get me started on stairs." she says, trying to put the man at ease.

She bends over and waves at the woman.

"Hello! Did you say something to eat? Yes please!" she says cheerfully. She can always go for a little more food. She's not too keen on the idea of going through all her rations before she's even gotten started on her investigation.
