Elgin seems to realize he messed up in season 4’s premiere, “The Arrival,” when the consequences of his choices start becoming impossible to ignore. The recent discussion around the episode points to that moment as the turning point, especially given how the story is framing his actions around the night- creatures and the sacrifice-related bargain.

What the discussion suggests

  • The clearest sign is that the show treats the premiere as the point where Elgin’s mistake becomes obvious.
  • Fan chatter around the new season is also focusing on that moment as the “big mistake” reveal.
  • Earlier recap coverage says season 3 already left viewers confused, so season 4 is where the payoff starts landing.

In plain terms

He doesn’t seem to fully realize it right away. The way people are talking about it, the “oh no, I really messed up” moment lands once the episode shows the fallout of his decision, not when he makes it.

Quick scoop

Elgin’s realization appears to hit at the start of season 4, when the consequences of his actions become clear.

TL;DR: He realizes he messed up in the season 4 premiere, “The Arrival,” once the consequences of his choice are revealed.
