Oof @miniature-tiger, this seems like a round likely to get us killed. Here's the pros and cons as I see them:

Option 1: We both have firearms, so that's good, and I presume the pistol is better at close quarters than average, but the rifle is not, and I'd kind of assume, if we're guessing, that the shotgun, with its stopping power is the possession that would allow a team to survive that choice. Or maybe they're friendly again. I know you were friendly. Though also, we don't have silver... if we need to bribe someone, I assume that's what they'd want.

Option 2: Grabbing a vine. I wish I knew more about this vine. The way it's drawn, it looks like a grape vine. I feel like that's a pretty weak vine. But does that matter? Does it actually wrap around the tree?

Option 3: If the drawing is to scale, the distance is just under 3 body lengths. Average human is 5'4", but it varies greatly by country, and we don't really know where we are, or who is represented in that picture. Anyways, that puts the horizontal distance at 15-20 feet. A world record running long jump holder could easily do that. The average person falls short by a couple feet. Are we average?

Option 4: I really want to trust that we have all the relevant info. The log isn't rotten, is it? Can we thump it to test it? It actually reaches the whole length, presumably? One of us can hold it steady? I've walked across lots of streams on logs in my life, so I trust logs, but this isn't my life. This is a game.

I'm inclined to 1 or 4. 1 because we have the tools to fight if necessary, which makes us special and makes it a special option... plus there's the possibility (though I think it remote at this stage) that there could be some benefit. There's no reason to believe they're friendly, but there was also no reason to believe that you were friendly, and you were!
And 4 because, of the escape options presented, this one seemed the most viable.

I have eliminated two options. You pick one of them. I'm willing to go first across the log, if you want me to.

...also, as long as I have your attention... you wanna read a story I'm telling over on my page? Here's the link. Ignore it if this feels spammy to you (also tell me. I'm still figuring out etiquette for posting links that I want to share). https://steemit.com/story/@improv/gentle-werewolf-scene-1
