James cannot come back. For the reason that some people would feel that's netorare. Main Girls cannot have any contact with other males, after meeting MC. I don't see DPC daring to enter a shitstorm like that.
How could he manage James living with Bella? James coming out as gay? He already used that trick with Chad. James having another girlfriend? So why he would come back?
James in a wheelchair, totally unable to have erections? He could still lick her pussy.
the problem is just that: how will DPC handle it. because the return of James could be very interesting, but I risk becoming a meaningless screaming scene.
so far MC's question about James has received a non-answer after 4 chapters that doesn't even clarify what exactly he was doing.
now if he came back after actually doing his duty, for the country, for God or whoever it was, Bella would look terrible in case she got distracted with MC in the meantime, but if there was nothing his return would be almost pointless and boring for all the games that avoided the beautiful librarian.
if the Christmas dinner flashback/flashforward is about him, which seems almost certain to me, it must be a more universal event, it must pose a threat to the entire BADIK microworld
but the danger of a meaningless ‘fuck, fuck, fuck’ is always around the corner
