There have been rumors that some of those developments will be linked to Snow White, as we said above, but it’s also been claimed that other characters could be affected. Hopefully this doesn’t mean that the producers are planning to get rid of any characters, however.
Some fans have speculated that the implications could be related to someone’s relationship, as there have been lots of possibilities for worrying developments on this front, but we don’t know exactly which characters could have their relationship negatively affected.
Most likely there will be a major plot development throughout the second part of the season, as this is a typical way for the writers of this show to handle it. It’s very likely that they are going to introduce some major plot line very soon, and that could be the rumored dramatic change that’s coming up.
But if the show follows the style of its previous seasons, then the new major plot line is going to span over multiple episodes but still come to a conclusion at the end of the episode, possibly leaving with a cliffhanger but still otherwise rounding up the entire season nicely. Whether or not this is going to happen like in the previous seasons is hard to tell but it’s definitely something we would expect from the writers of this show.
