Luke has been wearing black Cons all throughout the series, including his solo episode, The Twin Thing.

In the finale, hes spotted with red shoes in the spooky hotel room scene.

Um, she went, The cake is red.

And on set I went, Oh, my God!

And she went, I dont know!

And I asked Mike [Flanagan], and he went I dont know.

Viewers have been fooled before.

As far as hes concerned, The story of the Crain family is told.

Whether that story had a happy ending or the one Jackson-Cohen suggested seems up for debate.
