The question we asked was about his location, incidental information on his surroundings isn't confirmation that there isn't anything else around.My understanding as quoted is that dude is literally out there in the open.
Nothing hiding him, you open a Way you'll see him.
So open Way, keep Way open, send person through to bag and tag.
The fact that J, a minor shaman, standing apparently undefended in the nevernever mirror of a relatively unpleasant location should be taken as a sign something we didn't see is defending him.
Even modestly nice bits of the nevernever are not kind to travelers, that's part of why wizards call it that.
The greater Akuma could scare off most things, but it's worth noting that the nevernever has plenty of hostile and alien stuff in it ranging from animal like to sapient but too alien to make the same risk assessments as a near human.
Letting him stand there undefended is like putting a purse dog on a leash in your backyard in coyote country.
By rights they should know better than to hunt near humans, but sometimes they'll still come eat your dog anyway.
All of which discounts the fact that he knows we're coming for him, should know we have people with access to the nevernever, and is in hostile territory regardless. He can't be sure that the appearance of weakness won't earn him a poke from the local powers.
The will of Kakuri could most likey win against that sort of thing, but it's still another problem he had to juggle. Something to handle it so he doesn't need to sit on guard duty himself would just be sensible.
Perhaps it's a bit paranoid on my part, but Micheal is sort of our big counter.-[X]Team 2: Molly + Gard + Murphy + Lydia + constructs + 1x Infantry squad: Torture room
--[X]Team 3: Dresden + Michael + 1x Infantry
I don't buy the higher end estimates of what a greater Akuma can do as being valid here, but if I'm wrong and the projections people like @Alratan have been making are close to accurate then Micheal and Amoraccius are most likely the only way we make it out alive.
For that reason I'm inclined to keep him close to Molly, because the Akuma should be familiar with this problem as well. Splitting us up and bogging Micheal down long enough to finish with Molly is probably their best bet for handling him in this scenario.
Putting him in the nevernever in particular is almost the perfect setup to take him out of the game till it's over. All they have to do is keep Harry too occupied to open a way out again.
