May be because Alisha still can't connect to Jolly and think it is unfair to other contestants. Those who think that Jolly sings better than Alisha should listen to Jolly's previous performances. Do we always support the one who sings best or do we have other yardsticks too? I think we do😃 and that's why even after singing bad some contestants still have supporters.
We here seem to get carried away with just one good rendition. Just one song doesn't matter. Let us wait and hear her for some more galas and may be by then Alisha will get comfortable with Jolly.
