The Remorseful Professor

Post-film.

A one-shot about Professor Robert Callaghan's regrets, shame, and grief. He mourns for what he's done, but little does he know he will get a chance to redeem himself.

I recommend you get some tissues if you read this.

Think of this like a small snippet to the upcoming BH6 story 'Prelude to the Nightmare Crown'.
