Yup Ahil is not in any team, stand by or otherwise. He is the one everyone is tricking and that means every one including Sanam sadly enough! As for revenge I'd rather people put the tortured living souls which is Sahil out of their misery by revealing the 'secret weapon' of the twin existence and the swap than avenge the murders that happened 20 years ago...First always must come the living compared to the dead...and the living should not be continued to be tricked and hurt to avenge a death.
