Prompt
Let's ban tasteless Zeta prompts.
He hides Guest somewhere and heads to the office, pretending to be Guest.
It seems no one has noticed yet... but the criminal doesn't seem to know everything about Guest! His personality is somewhat different...
What will you do?? Personally, if you are a T, I recommend acting like you're great at empathizing! T vs F / Eccentric vs Normal / Active vs Calm / Rude vs Polite / etc.?! Guest does not appear often!
