Hey now don't forget about Downy sitting in his little corner of the city all by his lonesome.
Mu is still under Downy's thrall, giving him a trained assassin using rune enhanced firearms and a pair of acquired noble phantasms (one of which the archer's can steal and one that he cannot, a weapon wielded by Izanami & Izanagi to create JAPAN[!] but given to them by the elder gods).
Well hey, maybe Ran could come with you! Ran doesn't exactly have any direction apart from "Landlady knows something", and once she talks to Forest she'll need something else to do, and helping handle the Downy could totally count.
This could also be used for them to encounter Seras, who better to meet with a Vampiress of one branch of vampirism than another vampiress from a separate branch. Though I might just have the Don pass them, while walking in the opposite direction and let Forest get a glimpse into the mind of the
man leading the criminal underground in the city.
And if there's already some rivalry going on, maybe she could just beat on his mooks instead. Everyone needs a good mook-beater! And who better than a dungeoneer, eh?
Careful, Mu already cut threw a swath of them and he got himself enthralled (though it was a coalition between the two of us though)
Oh! I just realized something, Lawrence is the only one to encounter The Don/Joe thus far and maybe Forest could pick up on a revitalized train of thought about taking
Mr. Fixit up on his offer. If you guys can do it, we could have Forest ask about the offer Joe made to Lawrence out loud and then we can let the others in on the existence of the man running the criminal side of Nexus. If possible can Forest see brief flashes of memory related top a train of thought? If so then when Forest asks the question about who Mr. Fixit is, she could get a memory
flash of what The Don/Joe looked like from Lawrence's point of view and she could describe what she had seen through Lawrence's POV to the others.
