No spoilers here. But this was a disturbingly satisfying episode. A plus +10 in every way. I can foresee much discussion about the last 10 minutes. However tonight I'm here to praise the Actors, the Director, the Writers, the camera work, sound & special effects. Excellent job by ALL the cast and crew. The music throughout the episode added so much with its foreboding low rumbling etc. I will be counting the weeks until Season 5 starts.
