The possibility that Ankita might act with Shahrukh Khan, directly puts spotlight on the speculation, whether she will manage Pavitra Rishta alongside doing films or will pick either one. She had recently left the show, Pavitra Rishta, for a while due to some script issue.
Again, recently, Pavitra Rishta did not show Archana in a few episodes. The reason behind this is speculated to be her attending the IIFA 2013 awards in macau with Sushant Singh Rajput. The story of the show was maneuvered for her sake. The episodes did not show her in person and said that she was sick and was taking rest in her room.
The show has been repeatedly changing scripts for her sake and the viewers have been patient with the whole thing. One of the reason for this patience being the following her character Archana has had from the beginning of the show.
The show has seen huge success during the time when Sushant Singh Rajput and Ankita Lokhande were acting in the lead roles. Then Sushant Singh left the show to jump start his movie career. We all know the later story about the recognition he has received so far in Bollywood.
Looks like Ankita too will be following Sushant's footsteps. If the buzz is true and Ankita will indeed be paired with the King Khan, the possibilities Archana might go back to coma seems pretty high.
All in all, we have to wait and watch what story unfolds in Pavitra Rishta as well as Ankita's career.
