Since the Kingmaker supposedly disappeared days ago you hadn't been able to contact him at all before your trial, right?

[It's the most obvious question he can think. He knows very well by now Black can't get in contact with the Kingmaker, buuuuuuut...if something can be done about that to take advantage of Black's status as a mole and supposing the Kingmaker doesn't know he got caught...but it is pretty much a last resort action. He'd rather Black to not to have contact at all with the Kingmaker]
