This is more observation than meta or speculation and based only on watching the episodes and my OCD-thinky thoughts.
That being said...there is always the chance that it is a spoiler for the storyline so I'm giving the courtesy spoiler warning:

POSSIBLE SPOILERS...please do not click the cut if you are spolier-free and want to remain so.

( O.k...I'm just gonna toss it out and see if y'all throw it back. )
