Not only he hid the fact that Reeva was alive, he also hid the fact that he is a widower. This happened before Reeva surfaced in the show.
He does not tell Sugni that he is a widower. Sugni finds a photo of him with his wife when they were in his bedroom.That time he handles the situation by telling her that the wife is dead.
When Reeva is discovered by Dhanuma, Vikram chooses to hide her in some old haveli and gets a wall constructed in a room so that nobody can gauge Reeva's presence there which was very inhuman.
He does not listen to Gulabiya when she asks him to tell the truth to Sugni.Moreover he arrogantly challenges her that he would influence Sugni in such a way that she would always believe him rather than believing her mother. He gets Gulabiya packed in a gunny bag in order to avoid her posing a threat to the marriage. It was good that Aditya came and rescued her else she would get suffocated to death.
