"It didn't say that."
"There was a line in the poem that technically said that."
"So you're asking me to change one line of the poem? It's not my poem, I just chose to put it on the mosaic."
"You could probably get the copyright holder's permission to do a modified version. Or use a different poem."
"The copyright holder is Sarah Flynn-Pembroke. She'll probably agree to do a modified poem, but I'll want it in writing that the changes are being demanded of me against my will so she won't hold it against me and I want a written disclaiming of creative involvement from the demon guy before I broach it with her because if he does wind up finagling creative credit for any of her work she will hold against me."
"In that case I think we need to escalate the matter to someone with the authority to formally demand the changes. Do either of you object to taking it to the station assembly?"
"I don't see a good reason not to just take it to the court, but if you want to make the assembly deal with a vandal telling a fantasy story it's not my problem."
