I had called it some episodes back (They F'ed up and released a promo of the Night King on an Ice Dragon), but still - holy hell. Seeing those blue eyes sent shivers down my spine. Ha.
Also, let's take a moment to appreciate this conversation:
Hound: Brienne of Tarth?
Tormund: You know her?
H: You're with Brienne of f***ing Tarth?
T: Well not with her yet... but I see the way she looks at me!
H: Like she wants to cut out your liver?
T: ...You DO know her!
