Helping Hoffman in his machinations - or is she? - is Jigsaw's ex-wife Jill (Betsy Russell), and with these three co-leads in place, Saw VI indulges in the most shameless explosion of flashbacks (yes! from three different perspectives) to various moments from the previous movies and to even earlier points in Jigsaw's life, which is how we learn that not only is Erickson a dick, he's also a dick who was very particularly a dick to a germinal serial killer.
