WWE Hell In A Cell

Last night was WWE Hell in A Cell, and from what I read, it was pretty interesting. Although I don’t understand the outcome of the WWE Universal Championship Match between Kevin Owens & Seth Rollins, in which Owens retained the Universal Title, also Roman Reigns retained the US Championship, the WWE Cruiserweight Chhampionship changed hands, and can somebody explain, how a Hell In A Cell match ends in a DQ? Like it did between The New Day & Shameus & Cesaro? And…I still don’t quite understand Enzo and Big Cass…But, big congratulations to Charlotte Flair on regaining the Raw Women’s Championship in the main event last night.
