Yeah, I'm going to go ahead and vote B on this. Rin has been behaving pretty competently thus far, she's certainly improved in facing the cloaked folks and I trust her to be more cautious among them now. (1) Besides that, people attack when you're at your most vulnerable, not your most able; as wide-ranging as these cultists seem to be, if they manage to narrow down the location of the village and know about the massive expedition, they'll be sure to strike and cause a lot of damage. Rin is durable as balls, the goblins and slimes and Zayan are... squishier. (2) Rin getting brainwashed and attacking us is essentially the worst case scenario and that's already happened with us being able to win out in the end (and now we have the gauntlet which could probably have helped out even more in that case) so I don't think there's that much of a problem with sending Rin out. (3) I'd rather her be on a high-level mission that she can handle rather than getting cabin fever in the village, anyway. As an added plus, if Rin's not around when the expedition shows up, that's much more XP for Trider and his subordinates to pick up on, and I'm sure she won't be missing out on gaining any herself when she's out in the wilds attacking those shady foes. (4) If she gets overwhelmed or comes across very important information, it's also easy enough for her to teleport back in the majority of cases. Actually,
treave, could we ask for Rin to zip back in and give a brief report to camp if she comes across incredibly important information to us at some point in her travel?
Alright, I am feeeling talkative today.
So let's see the pro and contra of this argument.
(1) Yes, allowing her to stay is a risk. Says so in the choice. The difference is risking the village vs. risking Rin - plus, having her to defend from several possible attackers vs. not having her around while only attacked by adventurers whom we've so far ignored. This seems to balance out.
Rin's durability may yet play a low-down trick on us. That brings us to (2).
We don't know the mechanism for brainwashing yet, and we don't know if that's what is Rin more likely to face. The second person didn't have anything on him, but that's not telling us much because he wasn't prepared to find trouble. However, so far we have seen the cloaked people are related to Byarlant, and Athos belongs to a Byarlant archmage, so this remains a possibility. Last time we were able to overcome Rin, but there were two factors playing in our favor - she was wounded, and she resisted the brainwashing, allowing us to strike her down despite being inferior to her in combat. While we now have Barbatos, it is unknown how much of an equalizer he would be were these two factors removed.
(3) I'll give you the XP argument. The halo upgrade is too shiny.
(4) Rin? Fleeing when overwhelmed? Do you remember our encounter in the Demon Palace?
Rina-fumblerina is also Rina-spacemarina.
My only caveat would be to give her some way of instantly communicating a crisis to us (an alert medallion or something). Not because we don't trust her, but because we're partners.
I'd be down with that, actually.
But even if we could create one, what are we supposed to do if we receive an alert and we don't know where she is or how to track her?
Zayan and Erdrick are fellow magical researchers/geniuses, they have something to bond over. Aria and Arlin are children, which means that they are malleable at this early stage of development. Rin isn't and she doesn't have much in common with us
Actually, Rin has more in common with us (and vice versa) than with anyone else in this world. To us, she is the only person who knows of our world and can relate to the events that transpired there, and so is Erdrick to her. It means a lot.
