Is Will's son biological or stepson? What do the books say?

Do you mean Wally? In the show he’s obviously a step son, I mean…He’s twelve. Will has been married for three years besides it is stated he’s a stepson. In the books it’s different but the show and the book are different universes, so no one in the fandom mixes them up nor is it logical to do so since book Hannigram doesn’t actually exist.

Yessss thissss. The show and book are definitely different universes and need to be recognised as such.

But on that note, he’s a step son in the book too, when Jack talks about him being taller than Will and Will says his dad was is a quote from Harris (I’m pretty sure) - but his name is Willy in the book. I guess the show changed that because it’s too similar to Will?

Will and Willy would’ve been ridiculous hahaha
