yes, it is rare to see as a pilot we have hired to protect us, he suddenly becomes our boss and we must "protect" him because if they will go with another commander, and possibly was thet he who did not do well his work, for example while I drive an SLF and he drives my ship.
I thought those NPC were "out of work" waiting at a station and that my ship's insurance covered all the components of it, like escape pods,
but it is more realistic to pay for your insurance, pay for your SLF (it doesn't even have its own), and pay the npc apart so he can continue working with you and you can continue paying him.
He/she is like a kind of God (with no fixed job) who never makes mistakes, you have to protect them when you thought you hired them to protect you.
