What if the whole sob story Wendy gave to Bae after "being let go" was just a big setup to seeing what he truly knew about magic and what he would do for his family/loved ones?
I was thinking at the time that something didn't seem right with the way Wendy was acting. It seemed like she was TRYING to get Bae to sacrifice himself, but then he came up with the way to save them all. Only it didn't work.
