The new s an Orlock bounty hunter with a pet, and an Enforcers bounty hunter with a pet. Neither of those pets are given skill lists, so I would infer this hanger-on pet to similarly not be intenddd to gain experience.
Edit: I expect we are intended to treat the Exotic Beast owned by a Hanger-On also as a Hanger-On, which means no experience gains. Again, was it Slate Moderna and Servallen who have existed for years without this really coming into question? Good catch. An example of needing a high “n value” for playtesting.
And on any lasting injury result that would make any change to a fighter card, they leave with their gear. I would suggest that memorable death would be a change to their fighter card, so their gear would not end up in your stash.
