Aligning an anchor's normal angle with the rotation of another object.

Hi, so I've set up some code so the ends of a path move with a given object, but I'd also like the normal at that anchor to match that object's transform.up (as closely as possible, as the normal should still be perpendicular to the curve). I can define an angle for the anchor point, but is there a way to set that angle so the normal matches the rotation of another object?
