I think they could've kept in Pallu's scene even after deleting amma's scenes.
As far as I remember Pallu only mentioned that amma had the same doubt on them. Nothing derogatory or even explicit 🤔
My theory is that Star felt that even a reference to homosexuality was 'too edgy' for them, and it's nothing to do with how terrible the Amma track was, and that's just a fortunate byproduct
