reasons:
a) there are rumors he is replaced because of...
b) he said "he might make a come back"
c) Hibaa apaa said said "he might make a come back"
d) there are other reports from his fans...
e) Khushab's instagram message...
at the end the first one is rumor
b and c doesn't count because it is obscure language...
d can't be verified
e is not even to be considered because it is just a statement...
at the end I am just worried because I don't want to loose Pearl bhai from the show.
So, the negatives are all based upon doubts and obscure language...
