@Lord Wraith AND EVERYONE ELSE, I'm just too lazy to ping you all.
I had a thought, actually, I had it before when talking about the impression Lucas would get off of Gareth's bag, and then forgot it and just remembered it while trying to sleep. So, uhh I should have been asleep hours ago and if this makes no sense, I'll fix it when I'm properly awake.
Anyway!
I was thinking that one way Lucas might make himself useful to the convoy is to vet people wanting to join. Sort of give them a slightly less intrusive but not really pat down of their belongings in an effort to make sure they aren't bringing along any unwanted baggage that could cause trouble later on. Of course, there's no guarantee that he'd catch everything, but it's better than nothing when trusting strangers without a few caveats is a bad idea.
I don't know how long he's been a part of this particular convoy yet, but I imagine he would have done it for the convoy he was a part of that probably joined up with Tarvos' at some point, so it could be a relatively easy 'tradition' to introduce.
Could be a public thing, just anyone wanting to join hands over their stuff with anyone else around able to watch and listen in, or might be a private affair with just them, Lucas, Tarvos and any other unofficial convoy leader, maybe. Dunno. Just figured I'd write down my thoughts before I forget them again or we get past the point of it being useful.
This would require some coordination on our parts, since I'd have to make sure I'm having Lucas say the right things. But I can leave out, or vague up anything that you want to be a surprise plot point down the road, provided I can think up some good cover for it, anyway. >.> Hopefully you'd help with that if my brain dies. It's relatively easy to slip things past Lucas though, if there's enough distraction. He'd be trying his best, but he's fallible.
Thoughts? Good? Bad? Forget I ever thought it?
