Say the scum team is Banana and Kohai. They have a discussion about which of them Pie is gonna jailkeep this time, but it's a total tossup, could be either. So they can't just send the one less likely to be jailkept to do the NK and use their Redirector on me. They're forced to use it on Pie.
Why they didn't just redirect Pie onto me is another question. Probably guessed awesome was actually in the guild.
This is a very good question. Possibly because they figured your results would be messed up again. Possibly because they don't know what Magic's role is and want to account for uncertainty. Also possibly because they want to keep you in the PoE.
