I counted at least four. Which two did you see? I might have missed an additional one or two. I’m not going to lie: “Five+ Hidden References You Won’t Believe!!!” is much better clickbait than “Four References You Might Not Get”.
The Wardrobe. – C.S. Lewis novel The Lion, the Witch and the Wardrobe. (arguably his best known work)
Bigger on the inside – common remark about the TARDIS.
One I just notice – Q. ST:TNG character.
I am not seeing the forth one. But it could be a fandom I don’t follow. 😉

[Note: “*Who* scored 800 on the Language portion of the SAT and *who* scored 530?” is NOT a valid defense because numbers make me feel bad.]

But if it’s in Pratchett and Peter Pan, I’m sticking with it. Anglo-philia FTW.
