Is Reza a prokaryote?
Assuming Reza didn't live in the man, then being a prokaryote and killing him would be near impossible... unless...
Did Reza come in direct contact with the man's body?
Was that the reason the man died?
Did the man name Reza 'Reza'?
Did someone else name her 'Reza'?
Does she even have a gender?
Is she of a race in which it would be suitable to name her as something?
Did the other man make her resentful of the first man?
Do spamming these random theories make you [insert negative attribute here]?
Reza is a large dog, owned by a criminal. The criminal used her as a guard dog for more than ten years, and since she knew no other form of life, she couldn't refuse. One day, the police came by and took her into their care. She was trained to become a police guard, and eventually tracked the criminal down and bit him to death.Is Reza a dog?
