They really gave Stiles magic for one episode and we all, collectively and rightfully so, assumed they'd do, you know, virtually anything at all with it so we took it and ran with it and fleshed it out beautifully and have hundreds of thousands of words written on Spark!Stiles and how his magic potential could have come into play in the show.
Meanwhile the writers room of the show were collectively picking their noses and brainstorming the worst ways to kill off beloved characters in dumbass plotlines.
I was so upset when I watched the show for the first time and NOTHING ever happened to expand further on Stiles having magic. Like, what? They introduced such a good idea and then completely tossed it in the trash after one episode. Then again, I think magical Stiles would’ve solved about 99.9% of the problems in the series, so maybe they were just afraid to confront the powerhouse that is Stiles with magic. ✨
