(( All depends on how you use it, I'll make my tomahawks work just fine. ))
"By all means, I trust you will have no problem with me calling you a monster from now on, if you can't show respect I see no reason why you deserve any.
"...We've both been calling them monsters. Everyone calls them monsters. Why are you picking now to criticize this?"
Wake Julia.
Exit the car, helping to remove all the supplies and such.
Claim one of the pistols for personal use and make it clear that I get "dibs" on explosives should a conflict arise in the future in usage.
As the train pulls away from the station, you shake Julia awake and take one of the pistols, loading it with seven shots before starting to unload the uncoupled storage cart, putting the explosives in a pile off to the side and writing your name on them. Yep, that'll stop anyone from taking them. Except maybe dyslexics. And the blind. And assholes. Well, it's better than nothing you suppose...
Walk out of the car, my personal Winchester at ready. Look around attentively for any hidden hostiles. Maybe I will be lucky too see them. If there are any at all.
You step out of the car and look around carefully, trying to spot anything that could possibly be dangerous. However, other than a couple of dangerously sharp cacti and unstable-looking buildings, the area looks mostly safe for now.
"Walk off the train. stand with the others and listen for sounds of movement in the town.
You try to pick up on any sounds over the banter of the group, but hear nothing aside from the occasional whistle of the wind as it passes through the holes in buildings.
Get our stuff, restock on ammo while I'm at it. Claim a toothpick, one of the pistols, and a can of beans while I'm at it. Yeah, the whiskey and the tinderbox, too.
The one flaw with the Lorenz is that it only holds one shot at a time, but you've used one often enough to know how to make that one shot count. You load it up, and keep fifteen bullets on you for later. You also grab a toothpick in case things get desperate when you're reloading, and a can of beans in case you get trapped or lost. Sadly, the whiskey jug's a bit on the heavy side, and isn't really something that you can carry around and still run properly with, but you take the tinderbox and clip it to your belt for safekeeping.
Julia wakes to someone tapping her on the shoulder. She blinks a few times, breathes deeply, and gets up.
"Rifle, sword, water. Nothing else," she murmurs to herself.
Take a Winchester and the cavalry saber. Help offload the other supplies from the train.
You take and load one of the Winchesters, as well as the saber. You note that the blade's actually rather blunt but heavy, probably so that it would do a lot of damage from atop a charging horse. Unfortunately, it's not the best melee weapon because of this, but you keep it anyways, figuring that the reach should make up for it. You then help Carl with taking the supplies out of the nice cool storage car and exposing them to the scorching desert sun. You're not entirely sure what the point of this is, but hey, if the group genius is doing it then it must be a good idea.
