Theories

JWJ wants us to assign each or some off the characters in this story to a constellation. It is just a matter of time figuring out who plays what part: Cygnus, Draco, Cepheus, etc.

Leo and/or Aries

In the episode five letter from JWJ in reference to Lloyd he mentions "He had a reputation as a Lion but he really was a lamb."

The Lion constellation is Leo and the Lamb constellation is Aries.

In the episode four letter from JWJ he also says "...laid frame to the next panel of our lives in the great cosmic mural."

I think this is leading us to look outside of our sky chart and the next sections over in the universe. 

Both Leo and Aries are right next to or in the middle of our sky chart. Possibly Lloyd is either Aries or Leo or both.
