I still think one of those establishing moments of Dunmeshi is when Marcille says "I research the most incredibly fucked cursed ancient magics. Is it ok with you if I employ them to resurrect Falin?" and both Senshi and Chilchuck immediately go "let's do anything except that", meanwhile Laios just shows a bit bewilderment and then goes "yes do that right now please" and Marcille just nods and gets to work.
That question was exclusively for Laios. Marcille and Laios are here for a very express reason. Everyone else is accessory to it. Essential accessory, mind you, because everyone's skills matter, but when it comes to the ultimate objective of this spelunking, that's Falin, despite the whimsical comedy of the rest of the trip en route to that final objective, Marcille and Laios are not going to pretend they are there for anything lofty or selfless: They are getting Falin out of there, alive, the natural order of things be damned if it must be damned for that to happen.
