Another plot twist might be that the person who gave Marsha the love potion was actually in love with her themselves. They thought that by making her fall in love with someone else through the potion, they could be closer to her and perhaps win her heart in the end. So, they watch in agony as Marsha falls for another, all the while planning to reveal their true feelings at the right moment.
One possible story could be that Marsha, as the Queen of Diamonds, is given a love potion by a jealous rival. This potion makes her fall in love with the first person she sees, which happens to be a commoner.

He shows Marsha the hardships of the people and she, under the influence of the love potion, starts to care more about the well - being of the common folk.
A great plot twist could be that the love potion Hermione is exposed to actually has a secondary effect. While it initially makes her seem infatuated, it's secretly stealing her magic.

They then have to race against time to find out what's really going on and reverse the effects before she loses all her magic.
Maybe the potion was created by a rival house as a prank, but it backfires in some way. The transformed Slytherin boys - now girls - end up being more popular or more successful in certain aspects, causing jealousy among the other houses. And then there could be a race to find the antidote before things get too out of hand.
One interesting plot twist could be when the polyjuice potion is accidentally modified. For example, instead of just changing a person's appearance, it also gives them some of the magical abilities of the person they are transforming into.

One possible plot twist could be that Ino is initially in love with Sasuke, like many other girls in the village.

Also, it could turn out that the father of the baby is not who everyone initially thought, leading to a whole new set of relationship dramas within the story.
