It seems Kapil Sharma has now given up on co-star Sunil Grover's return on his comedy series The Kapil Sharma Show. Yesterday, a fan took to Twitter and requested Kapil to bring Sunil back on the show. Kapil replied him politely and said. Sunil Grover quit the show after their ugly fight in flight. Kapil also tried to apologies on Twitter, but it was too late.
