Red is not Red

In keeping with the "Red isn't really Red" theory, here's a thought. Let's just assume this theory is what the writers have in mind. Is it possible that some of the things we see Red do, certain people he interacts with, or certain memories ( Ex. Ballet, daughter Jennifer) have absolutely nothing to do with the Liz story line? Could these things only be of importance to the impostor? Have we been collecting all the clues and wasting time trying to connect these things Liz? If this is the case, have the writers been throwing out reveals that will end up not relating to the main story arc?
