Depends, I just meant a possible split in character paths like how unredeemed Jessica was basically a mess. She was dead inside and if Ash moved in with her, her life was shown to be spiralling downwards. The redeemed version was happy and loving, supported Ash and was a much better version of herself.
With Ivy, i feel she may end up spiralling down in the game at a later date. I could be wrong but her lifestyle with the drugs and doing more and more questionable things to make money, perhaps Lena might be able to save her later on before someone like Seymour gets her (Lena is on a very slippery slope with him herself) If Lena lets Ivy influence her to much, I could see both of them going full slut path and getting into bad situations.
just musing.
