Gauhar and Kushal, as we know, gained their popularity with their love story during their stay in the Bigg Boss house. So much so that Gauhar went on to win the show while Kushal made it to the final five. This popularity was what Ajaz wanted when he started with the pretension of being in love with Gauhar and being heartbroken when she picked Kushal and so on.
Ajaz tried his level best to grab attention (and footage) by getting involving himself in this popular love story. Though the couple tried their best to ignore or pretend Ajaz did not exist, he forced himself into the picture and even managed to make it to the final five too.
Looks like the same is repeated in Khatron Ke Khiladi 5 now. Ajaz is entering the show as a wild card entry. What is interesting at this point is that Kushal exited the show on the very same episode.
Kushal, as shown in the previous episode has hurt his shoulder and the MRI results say that he better restrain himself from putting any more stress on it. This will mark the exit of Kushal from Khatron Ke...5.
Now the question is, was the shoulder injury just a cover up to not face Ajaz again on the show? It was pretty obvious that Kushal could not stand Ajaz and his stunts in Bigg Boss and there is a clear possibility that Kushal quit the show, KKK 5, stating an injury.
