Ohhhhhhh, I like this & now wonder if Killian’s ‘We can smash it’ line might not really be foreshadowing after all & why we havent seen much of him filming outdoors with the others recently, if he takes the brunt of the evil shards, it;d certainly require Emma to fight for them/him in 4B….
All of the possibilities for the mirror that you laid out would make for fantastic television. I could see something happening where the shards go into everyone’s hearts (except Emma’s and Elsa’s), and I could also see someone smashing the mirror (I wonder if Hook’s line about smashing it was foreshadowing?) and taking the brunt of the dark magic. It has the potential for some amazing acting moments, and I am so ready to see what happens.
