She won’t.
She snuck in under the false pretext of playing as a proxy for Eijaz, and is now enjoying the benefits of a full-time contestant. Eijaz is not coming back, and Devo is no longer playing for him, but her for herself now.
If this is what was required to raise the TRPs, then Arshi was doing well on the show by a mile. No one cared about Devo’s exit in Season 13 or her “re-entry” in Season 14.
Arshi, on the other hand, left a void in the game with her exit and added glamor to it when she returned. Nalla BB nalla hi rahega!
