If you kill one of them, you kill half of the cast with them. Remove Ian, you remove Emma, Perry, Wade and Cindy (the model rivalry is underdeveloped and a sidething), Alison, Cherry, Minerva, Jessica. If you remove Lena, you remove Axel, Seymour, Stan, Louise, Mike, Ivy, Ed and Molly. You remove either Ians book and tpurnament career with all its characters, events and gameplay, or Lena's music and modeling career. The game would end as an unrecognizable ampituted multilated monstrosity beyond recognition.
