I'm looking to make a cable with a semi transparent outer sheath, and need the able to move and curve the cable. In order to have the sheath move with it, I'm trying to move a parent curve, the child curve being inside of the parent, and have the child move as the parent would. Is there any way to do this or do I have to manually copy every movement of the curve with the handles onto both curves?

With the Hook modifier you can parent the vertices of 2 separate curves to the same empties or bones.
If you want to parent a curve vertex to a bone:
- Disable the Lock Object Mode option:
- Select the bone in Pose mode, shift select the curve, go in Edit mode, select the vertex, press CtrlH > Hook to Selected Object Bone:
- It has automatically created a Hook modifier for the curve:
Move the bone, it will move the vertex, the advantage compared to a hook to empty is that you can always come back to the bone rest pose:
- To hook to an empty you just need to select the curve vertex and CtrlH > Hook to New Object, it will automatically create a new empty:
Now you can hook the vertices of the other curve to the same bones or empties.
