When Jack put the red blanket on Joke, I noticed Joke has a little J with a heart tattooed on his shoulder, which I got a glimpse of in the second episode.
He doesn't have a chip on his shoulder. He has a heart on his shoulder. He wears his feelings on his shoulder. In his color.
And it's a J.
There is no Joker of Hearts. There is only a Jack of Hearts!
The Jack of Hearts sits on Joke's right shoulder which is normally concealed.
And the Jack of Hearts represents young men in love.
Every tattoo Joke has is about Jack.
Joke fell in love in one night five years ago and has been thinking about it ever since.
And that's why the ring with Jack's name on it belongs on Joke's finger. He already has Jack tattooed all over his body. Now he just needs Jack to allow Joke to permanently place Jack's name in his heart.
