Yeah, some fun-and-engaging kind of correction that includes Angry Anastasia, a soundproof basement, plus a few goodies such as a torch, a 650 amps truck battery, jumper cables and an industrial-grade shovel (non-comprehensive list).
It would be blamed on Anastasia or her family and lead to the things MC is trying to prevent.
The MC has to walk a fine line to make sure he can advert disaster but also not call attention to himself or his plans. And out right murder would be the opposite of that.
