After kidnapping Norman (Freddie Highmore), Romero (Nestor Carbonell) calls him a "sick f**k". This is the only time in the series that profanity stronger than "sh*" is used.
Dylan appears shirtless in one scene with no tattoos where in the previous season (4) he appeared shirtless with Emma revealing tattoos on his upper arms and rib cage.
People that are highly rating the end of this season need to be in an insane asylum
Poorly executed final few episodes with good music. No spoilers here. If you've made it this far, I'm sure you'll have a few head scratching moments as I did.
