Blood Type E and Imaginary Friends

Landon: "I have so many energy, my blood squirts it out."

Landon to Maura: "I saw Rick and Disappear walk by you and say you were weird." Upon hearing this she burst into giggles because Rick and Disappear are L's imaginary friends. They aren't too smart to pick on Maura because I have seen her go out of her way to accommodate these imaginary friends, even pushing them on the swings and holding their hands.
