In the series' version of Brother and Sister, one wonders why Rose/Sister was able to pull an Astral Projection to breastfeed her son despite being kept prisoner in a foreboding mountain (in the original she was murdered, and the one feeding the baby was her soul). It may be possible because the one who kidnapped her was the Wicked Stepmother doubling as a Wicked Witch, and her lair is located in the same mountain when Rose is being held... therefore it's likely that the mountain itself had at least some magic of its own, which coupled with Rose's extremely strong maternal love for her newborn and her desire to protect him even when she's far away, let her pull the trick at huge risk to herself.
While we're on the subject of Rapunzel...the narrator takes great pains to tell the audience that the Prince and Rapunzel married, right there in the tower, seemingly without benefit of clergy. At first blush it might seem like a way of getting around the idea that their child (only one in this adaptation...down one from the twins of the original Grimm version) is illegitimate. But the story also takes place in medieval/Renaissance times, when a promise of marriage was considered every bit as binding as marriage itself (pre-contracting, they called it).
Funny how this version of Bluebeard doesn't break out the Secret Test of Character every other wife has failed up to this point until Josephine starts acting like a huge jerk and getting on his nerves, isn't it? Kind of makes you wonder if Bluebeard was just waiting for the wives to become haughty for his excuse to kill them.
Brother and Sister has the Sister announce that she lived alone when she heard a knock at the door. Imagine if somebody less savory than the King had been the one to knock...
In the original Japanese version of Bluebeard, when Josephine refuses to wear her white dress, the first thing the title character says upon seeing her is bluntly asking she why she's not wearing her white dress. At first, it seems odd that Bluebeard would even have so many dresses and ballgowns available if he wasn't expecting Josephine to wear them. Then, you realize it makes perfect sense that Bluebeard's castle would be filled with discarded women's clothing...whose original owners have seemed to go missing...
