Mentor!Caretaker-turned-Whumper
Caretaker-turned-Whumpers that used to be mentors. This could just apply to any overprotective Caretaker-turned-Whumper, but I like to imagine it as the Whumpee’s past mentor/teacher.
What about Caretaker-turned-Whumper who used to be Whumpee’s mentor, then one day Whumpee was taken by someone, and ever since they gotten them back, they became... different.
Once they have their precious mentee back and safe, they become overwhelmingly protective. They take Whumpee away from their friends and family, and force them to move somewhere secluded where Whumper will never find them both.
Bonus points if they still try to mentor Whumpee with what ever they teach them, but Whumpee is more than reluctant to pay attention or cooperate. It’s up to you what Caretaker-turned-Whumper would do about it.
Bonus bonus points if the original Whumper is already dead (because they killed them), and Caretaker-turned-Whumper just wants an excuse to keep Whumpee hidden away and guaranteed safe, even if the threat is gone; because no matter what, something will always be a threat to Whumpee.
“No one’s looking for you, Whumpee, no one except Whumper. Do you really want to go back to them that badly? What if I send you back to them, would that make you happy?
“Then get back inside. Right. Now.”
