There are two paintings outside his shrinks office, both depicting a barn scene, might be jumping the gun but I wonder if there is any correlation to the future barn scene
Or
one painting depicts 4 children/figures, 3 heading towards the barn, and one standing on the fence isolated... the next painting is 3 of the children/figures playing on the other side of the barn, the 4th one not to be found... possibly hinting at Elliots 3 alters, leaving his true self on the sidelines?
