So Gangiya was telling the truth to Loha when she gave him the address of the place that Laali was supposed to be dancing.
And Laali was there at this place, but she hid from Loha and his men as they walked towards the dance performance. (Again this was the scene lifted straight from Ratna's wedding day. The empty chair in the background was where Shekhar had been sitting, and then had walked away in tears as Laali danced for the men.)
Therefore, we can safely assume, Gangiya has not really changed up till now.
The next test for Gangiya's change of heart is the Sumitra affair.
Is Sumitra really dead, as Gangiya had claimed?
Was she really burning Sumitra's body in the hut after sending all the men out?
