Does Toryn Farr only work for friendly ships at 1 - 3 or does she also work for the ship she is assigned to/put on?

If I put her on Home One can Home One re roll a blue dice each attack?

Another Friendly Ship or Squadron

She does not work for who she is attached to.

RRG, Page 6, "Friendly and Enemy"

Friendly and Enemy

All ships and squadrons in the same fleet are friendly to each other. All ships and squadrons in an opposing fleet are enemy ships and squadrons.

• A ship or squadron is friendly to itself and can be targeted by an effect that specifies a friendly target unless it explicitly specifies “another” ship or squadron.
