@queerlyalex is mentioning crack theories for who the beast is so imma just throw my hat into the ring here:
Coach Finstock is the beast.
Let’s review the facts:
- Mysteriously absent for like… 4 years now.
- Definitely has the internal rage that would lead to killing people. Like hundo p has that.
- Probably used to being drunk and then waking up in unknown places. Would not question were it to start happening again.
- We know nothing about his medical history. Or any portions of his history really.
- Have never seen Finstock and the Beast at the same time.
Conclusion: Coach Finstock is the beast.
