Is there ever any explanation anywhere as to who the hell these two are? It seems like they may be tribals, but I have no idea.

They are slavers at paradise falls?

what more do you expect?

I certainly expected more than "Hey, we're just going to leave these two weirdos here at Paradise Falls and give no explanation. Love, Bethesda."

I know it doesn't matter in the long run, but I'd like to know.
