Yes lovely! They built up a bank of Armaan scenes when Apoorva was away so why not the same for Mr soni?
i think the reason is first jjkn was put back to 3 days a week (becuz of indian idol--the show they once agin copied frum western tv) and they probably recorded ss only enough for 3 days a week. And all of a sudden they change thier mind to four days a week so they had no other choice. I'm sure if they made thier minds on 3 or 4 days we wouldn't have to face this problem. I'm not sure if this is exactly what happened but this is as far as my logic goes.
