Yes Molly is normal now, she doesn't even have her iconic pink hair. She spent time with her mother and it would seem her more entertaining and memorable antics will be mellowed or put aside... no more lovable nympho who loves to have sexual fun.
Yes, well... all we can do is keep the memory of Princess Molly in our hearts. Laughs, while I also respect and defend the real Princess Celestia against those who would make mockery of her name or criticize her character.
