After watching a couple of episodes of this season's Heroes, I wondered what happened to Mohinder.  Some people may have different opinions of the character, but for me it just wouldn't be Heroes without him.  Kind of like it wouldn't be Heroes  without Peter, Hiro, Noah, and Syler.  You asked, what about the cheerleader?  Heroes can do without her.  Her story arc is out and it was cool the first season with  the "Save the cheerleader, Save the world".  She shouldn't have lasted four seasons.  They now give her this lesbian interactions. OOOHHH!! NOT. Back on topic, what happened to Mohinder.  I miss his voice overs in the beginning and end of the shows.  He's like the intellect of Heroes.  He's the one that was supposed to carry on his father's work.  He was supposed to understand the special people.  This season we get nothing.  There is a rumor that someone was going to die.  And from what I hear, Mohinder is not that person leaving the show. I saw the show last Monday and to my surprise my question has been answered.  Mr. Butterfly as Hiro calls him has killed Mohinder.  So that's why we don't see Mohinder in any of the earilier episodes.  He died 8 weeks ago.  Well looks like Hiro will prevent the Circus man from killing him.  All that matters though an original character did not just disappear from the show.  Good one writers.  Now just give him a good story arc and will follow through the rest of the season.
