Well it all gets very confusing. As far as I understand it at so far. The party host had decided that d was a problem but later came to realise that a.b.c were the only people who have a problem with d and that the problem is there's and that d in fact isn't a problem.

In the meanwhile, d who we now know is not a problem remians locked in a room and is held by bouncers, some of whom we have learned are like pit bulls.
