Edo queries:

Can an Enforcer swims?

Well, lessee...  Jake's definitely a strong swimmer, and Commander Feral
and his niece seem to possess *some* sort of swimming ability (they
haven't drowned when they've been thrown into water), so it stands to
reason that perhaps the Enforcers must include swimming as part of
their training.

Or they once learn on how to swim before they join the Enforcers. Feral and
Felina maybe once swim together while Felina was a kitten, and maybe Jake
once swims with his brothers, sisters and cousins. (Don't know why I always
think that Jake has a big family, I just got the impression that he got a
big family)

Still, that wouldn't explain why *Chance* can't swim,

If he can't swim, I understand (a lot of people don't admit that they can't
swim), but he can't swim and managed become part of the Enforcer?

unless he managed to marginally pass the Enforcers' swimming tests or
lied about his ability to swim when he joined.  <shrug>

Well, maybe he got some help on becoming an Enforcer.
