Haha, sorry, I was just wondering if there was anything plot significant he could stumble upon, but I didn't word that very well. What sort of intel would Lucifer request?

And depends! Would Lucifer have provided something to make harming Mammon possible? Or have given any other instructions around proximity to Mammon? What exactly does he need done before he can deal with Mammon?

If there's anywhere specific Mammon's holing up during downtime/doing his pet projects, Rorschach'd try to follow Mammon there so he can have a pick about.
