On the contrary, right now I feel Imlie is not doing anything for others she is just focusing on herself and her revenge on Aryan. (How ironic Aryan wants Imlie to choose herself when she is making decisions and making her own choices, here she is choosing to be with Tripathi's and save Aditya. ON other hand Imlie want's Aryan to leave his revenge but her actions are truly because she is seeking revenge on Aryan), older Imlie wouldn't have felt so relieved after Aryan ask her to make choice, neither she would have done what she did at the Recaption party. Have you noticed the look on her face when Narmada called Imlie's name when she entered in her old outfit and cleaning stuff, as if she realized what she had done just to put Aryan down? she is fully not there but she is slowly changing and turning into AKT and unconsciously that's Aryan want her to be "selfish"
