That post about Marcille and Laios' relationship actually got me thinking about Chilchuck and Laios' relationship. Which is harder to see in some ways because it mostly consists of positive absences.
At first, viewers might be inclined to wonder why Chilchuck sticks with the party. He says it's because he took payment up front, but he could give back part of the deposit and leave. Two other party members left; Laios explicitly gave Marcille and Chilchuck a choice as to whether they would stay or go, and they both chose to stay.
We know why Marcille chose to stay; she wants to save Falin and she considers the other party members her friends. Why did Chilchuck stay?
Chilchuck actually respects Laios a lot -- food and monster weirdness aside -- and that mostly comes I think through the positive absences from above. The things that Laios does not do.
- Laios doesn't deliberately expose Chilchuck to danger or regard him as expendable. When Chilchuck starts to get enthralled by the sirens' song, Laios immediately snaps him out of it. Contrast that to Chilchuck relating that other adventuring parties will sometimes bring half-foots along just to sacrifice them or use them as bait!
- Laios doesn't insist that Chilchuck put himself in danger by getting into combat. Even in situations where they're in danger and could really use more combatants, he only ever asks Chilchuck to take on non-combat tasks such as creating distractions.
- Laios doesn't get in the way when Chilchuck is working and follows his directives of what to do around traps. He respects Chilchuck's work so much that he will even hand over his sword without hesitation, even when doing such a thing causes it to be damaged!
- Laios doesn't press Chilchuck to divulge private information. When Chilchuck says he doesn't mix his professional and private lives, Laios respects that and doesn't push.
All the other party members infringe on these boundaries in some way. Izutsumi tries to egg Chilchuck into combat; Marcille pries into his home life; Senshi deliberately provokes him when he's trying to work. Not Laios. Once Chilchuck sets a boundary, Laios does his best to always respect it. (And I think Laios appreciates having clearly defined Rules For Chilchuck.)
Laios is a good party leader and he takes care of his team. Maybe this is my age showing, but when you find yourself in a good work situation with a good boss, you stay in that job.
