Trivia

 * It's a possibility that Rhonda was not very close to her mother, due to the fact that Bertha must have died breifly before the events of Dead Rising 3, because her body was in a cremotorium but not yet cremated. However, Rhonda never mentions her nor does she ever appear to be troubled about it during the game.
 * However, it may be the case that the outbreak has her focused on survival, with no time to dwell on it.
