It seems that Lena attends the event no matter what, but if she's distrustful (or has Seymour contract ongoing) then it's just a "vacation trip" for her, tagging along with Ivy for fun at Ivy's request. Instead of going to do any actual photo work.So I am confused. In my pure Ian/lena play through I distrusted Billy and was not going to model for him but Lena still seemed to be going with Ivy. Am I just forgetting something where Lena decided she was going to Billy’s no matter what?
