I just watched the episode where Grace's boyfriend gets into a far off college and Abigail's love interest decides not to move to Middleton. I thought it was great, and noticed that it highlights a more subtle 'magic', where the Grey House women manipulate events and the price that is paid for that manipulation. Abigail was so determined to have her love interest (don't recall his name) stay in town that she manipulated events to speed up the process. Who knows if she had let nature take its course, what would have happened. Now no one is going to buy the mill, which would have helped the town. I actually wondered for a moment if the love interest had contacted the other buyers to make up for changing his mind, and then Abigail sabotaged that plan.
At the same time, we see Cassie letting things play out with her fiance, not trying to make him create a shorter guest list, and going with the flow. And it works out for her in the end because they end up on the same page.
Then we have Grace, who is still learning about manipulating events, her ability to do so, and whether the cost is worth it. I find it interesting and entertaining.
