KC makes two separate trips to see her children and mother in the movie, but in the second sequence all the actors are wearing the same clothes they had on previously. What's more, when KC makes her first visit, she drives to the location, yet her daughter is seen waiting to say goodbye next to a taxi cab. When KC makes her second trip, that's when she takes the taxi.
After Big Bertha defeats her in the grudge match a reverse image of K.C. is shown laying across the track with her splint seemingly on the left wrist and her number 11 backwards.
