THANK YOU! Every single time that I read a news article that talked about how no one saw this coming, I literally wanted to scream at the top of my lungs. We never saw it coming because the original comments on the play did not seem to hint at it at all! However, looking back -- a sequel kind of makes sense with the lines "of the
now legendary young wizard." Note to self: completely dissect every single word that JKR dishes out.
Almost every article I read focuses on his son and assumes the story will follow Albus when the synopsis clearly focuses on Harry. Regardless, flashbacks of young Harry and the Battle will be necessary for anyone who's been living under a rock and isn't familiar with the fandom.
*after dissecting for about 15 minutes*
Uhh, you might be on to something! It could very well star both young Harry and adult Harry! Perhaps that's why they split it in two parts? Ugh, I forgot how neurotic Harry Potter theorizing makes me...
