Easter egg city. There are many through out every episode if you watch the series close enough. The names of the Eagon family are peppered here and there ie; the name of the local bar, the name of housing developments where they live, street names shown on street signs or other random signage, the names of schools, etc. There are lots of things that are easily missed, you have to pay attention to alot of the simple details. Very clever writing.
Also watch the individuals that pass in the background of crowd scenes, these people are there for a reason. Remember those faces.
Anything Helly does is suspect for questioning what she's up to in season 2. Watch her very closely. She's up to something. Is it Helly or Helena?
"Metalhead", the story about the persistent mechanical dog on a mission to do his thing. Totally unexpected what this episode offered with it's storyline. Can't wait until season 7!
