Gopi's pallu, Ahem's mouli

couple of questions:

Which episode did Gopi start wearing pallu. In early episodes (julne 2010) and earlier, I did not see her wear her pallu even before Ahem.

Gopi ties mouli on Ahem's hand. did Ahem react about it next day about how it got there?

Chirag saying immediately after she took back her vows, as Gopi will be staying here not as your wife, I don't think she needs to put pallu on at all, as she will be a family member as I will adopt her as my daughter, after all I have one son only and no daughters, we will educate her and when she is finished that we will look to find a suitable match for her outside, then Gopi starts learning and Rashi's jealous of all Hetal and Chirag give her in gifts etc, so she carries on kalakaries then Gopi goes to school and Rashi does cheating kand and Chirag can't attend the school, Aham does speaks to the principal, as though they marriage was dissolved, now that she is no longer his, he has been observing her and gets to know some of her qualities so he defends her to the principal, then he tells his Khaka, as I was good at school, I can teach Gopi to pass the test etc so the track comes back to as it is now but these two would have been not husband and wife then when Gopi finishes her studies Chirag and Hetal find a suitable match for her, and Aham is unhappy, as he has gone really attached to Gopi during the education track, when it's her engagement he quickly confesses his feelings and Gopi also admits she has always had feelings for Aham and instead of getting her married to someone else, the marriage is between Goham, a remarriage. 😊
