Called a friend to hear about his studio experience in II2 Mar 7 result round and this is what he told me -
There was a discussion (rumor??) in the studio that the votes were mistakenly interchanged between Panna and one of the saved contestent who is now out anyway. They might go on to disclose this in the next round with a call back to Panna and he will perform.
It sounds like a rumor but might be a game plan from the organizer seeing the going down popularity when all suckers are remaining for the finals, Karu excepted.
