When I first read through the end of Coup d'Drow, I hadn't been keeping up on a day-to-day basis, and so I was taking several strips one after the other. But something started bugging me, and I didn't know what it was at first. I recently took some time to re-read, and pay attention - and it hit me.
Strip 2188: Wedding DayAm I the only one who doesn't understand how Mrs. Bloodhand wouldn't have known about this facet of Orcish custom? Had it been Bob, Gren or Bob2 on the receiving end of the exposition, it would have made more sense, but Mrs. B? Especially given that part of the point of Arachne's little plan was to obligate the Bloodhands to come to the aid of the Drow if, say, the Hobgoblins, decided to bump them off. And if we assume that Mrs. B needed to be told, then it seems that Arachne's plan is already in jeopardy, if the Queen of the Orcs (and Black Mountain besides) is unaware of the very bond that Arachne's attempting to create.
