It: Welcome to Derry episode 3 adds needless meaning to Bill’s slingshot

The joy of It: Welcome to Derry is how the HBO prequel series expands on the terrifying story created by Stephen King and brought to the big screen by Andy Muscietti. Now, three episodes in, we know how the Hanlon family wound up in Derry, which character connects the Maine town to the Overlook Hotel of The Shining, and even met a horrifying non-Pennywise version of It in the latest episode. And while that’s all great world-building, there’s also a line when it comes to creating new lore in the King universe. Unfortunately, Welcome to Derry might have just crossed it.
