SummerSlam saw Jon Moxley beat Seth Rollins and Penta beat Rey Fenix. Bad Blood Night 2 reversed both pairings: Rollins defeated Moxley inside Hell in a Cell, while Fenix defeated Penta.
That is a useful reminder to resist permanent conclusions after one meeting. The Cell adds a significant change to the Rollins–Moxley comparison; the brothers supply a second example of a rivalry moving in the opposite direction. Toronto gives both SummerSlam losers a direct answer without erasing what happened in Chicago.
