Why, why why. Why people, why would he confess to being a redirector of his own free will if he was Mafia? It doesn't make sense.
Magnus says he was redirected by someone (Dedede was most probably roleblocked so not him) who HAS NOT come forward to say he did this!
So either this other redirector is the Mafioso, or Magnus lied.
Fuck, this lynch is stupid.
