After the events of episode 5, episode 6 is a welcome chance to emotionally recover. The Storm half of the episode is a 10.
The line about demons...hot fire. Loads of quotables on this side of the episode.
The other part of the episode is a 7, only because it felt like it came out of nowhere (perhaps it's a comic storyline that I am simply unaware of). The two mesh together well, though. This definitely had it's moments, one surefire meme-able quote will resonate around the internet for years to come.
As was stated by Beau - 8, 9, 10 are the ones to rival episode 5. I look forward to what 7 brings to the table before we have to get our service animals, pills, tissues, and appointments with our therapists.
