why apu-shilpa got eliminated frm NB?

guys i think they wanted to leave the show....as in yesterday's episode he was like i dnt even hav time to eat n sleep....n apu was lookin sooo tired sleepy.....becoz how cud tht be possible....they hav almost the highest votes everytime.....n their performance wasnt soo bad that audience wnt vote for them....n apurva fans wud vote for him even though he gives a bad performance.....so y didnt they vote for him yesterday.....how can shipa-apurva get the lowest when they were always no2 to go in the surasha circle....it just doesnt make any sense....how can they get less votes than rajiv-delnaaz....impossible...thats wat i think guys...
