Whether Rose has been in the hold for a while or not probably depends a bit on how Thufir weighs in. Whether she's been local for some time or a newer arrival, however, it's totally possible they could've met outside earlier. She was wandering for quite a while more or less on her own before she got to Marco's hardhold (whether that's only been a few days or a few months from the present). Could've talked him out of some trouble his not-always-sensible way of talking got him into, maybe? Steered him away from something that could've turned ugly? She might not be steeped in the Maelstrom herself, but she's got a healthy respect for folks who are tuned in to the world we can't always see. Definitely plausible that they could be on friendly terms, or at least know each other on more than a passing basis.<br/><br/>(I suppose it's also possible they could've met on less friendly terms, but Amanuel doesn't seem like the type to purposely pick a fight, am I right?)
