I think Emon's wish on II was to meet his Idol Sonu Nigam. He knows he will be a singer irrespective of whether he participated. Emon did not just have his wish fulfilled but his Idol even compared Emon to himself. What more could anybody ask for? Sonu has many a times told contestants you sung better then me but he never compared any singer to himself like the way he compared Emon talking about his pitching, harakatein, etc. Moreover, Sonu even gave Emon his lucky charm. The topmost playback singer in the country giving this 18 year old such a token has to mean something.
Moreover, he got to sing in front of the best playback singer currently, best lyricist and one of the top 5 music directors in the country. How many reality show contestants get that privelege?
For me Emon is going as a winner as he has only gained from the show.
