Why Amla? Coz her marriage to Veer is illegal, not valid, second Icha may return bundela house soon. So Amla will left alone, so she may choose tej. Already we saw tej's inclination toward her.
Why Mukta? Tej is adamant for young girl, Mukta is looking for opportunity to get icha's rights back to her.So she can do some deal with tej.
If its Mukta, den its de grace.
