Q5

Why does Jennifer give drugs to the detached penis and what happens to Batz?

Jennifer administers drugs to the detached, dying penis in an attempt to revive it, believing she can control or cure the strange phenomenon. However, the drugs cause the penis to rejuvenate briefly, which triggers a fatal overdose for Batz, who is still connected to the organ despite the physical separation. This action directly leads to Batz's death, demonstrating how Jennifer's desperate attempt to satisfy her needs destroys both of them.

  • Batz death
  • penis death
