Hii
apologies I need to prepare an updated walkthrough for that xDD
tomboy is a definition you may find quickly in internet 😉 As for the girls you need to talk with to complete the mission, you may ask Boudicca in the campsite, or Captain amelia, if you have completed the haunted house sidequest, which will open an option in the menu to ask her for a favor.
Hope it helps :D
Merry Christmas!
