Answers always lead to other questions and here are some more:

Q: Would they care about leaving the horse behind?

A: Yes they would. It's the only other family that they have left.
Plus they would feel more comfortable riding the horse.

Q: Do they want to join us?

A: They have no where else to go now, and now no home to live in. So
they would rather take their chances on the road. "They want to go
and learn the ways of the force, and become Jedi like their father
before them."

Q: How long do they want to stay with us...to the next town or do
they care?

A: Until they fill like leaving, or until you are killed. Which ever
comes first.

Q: If we come across zombies and have to fight them are they ok
killing them? (harm own people) or would they rather just be support?

A: Zombies are zombies. Those poor souls would be better off dead,
since they are already walking dead. Unless there is a cure or a way
to save them, but no one knows if that is even a possibility. Maybe
one day. They will support. They don't consider themselves frontline
troops.

Q: What kind of other traditional weapons does she know?

A: She says that she knows how to use bladed weapons and sticks.

Q: Do either of them know how to drive?

A: No. Gas is hard to come by, and didn't offer them many
opportunities to learn.
