I have complete faith in Lord Ayyappa. If it is a blunder then he will punish the person. If its not blunder and that is "dharma" in this yuga...nothing might happen. Whatever happens should be endured in this age. Let us not worry about whether its a sin or not. Whether she went inside or not. Whether she touched the idol or not. Whether she tells the truth or not.
As far as i am concerned we should not be questioning the cult and the rituals that has been there for ages.
