Warning: This article contains major spoilers fromStranger Thingsseason 4, Volume 1.

If we’re going that far back, we might as well visit the one that started it all.

Bower’s face first shows up in season 4’s fifth episode.

So, she floats in a water tank until her mind drifts to the past, which includes 001.

But 001 appears in season 4 as a friendly orderly at the lab.

Vecna, the new demo-creature, is revealed in the latest ‘Stranger Things’ season 4 trailer.Netflix

(Even the end credits on most episodes state Bower plays a “friendly orderly.")

He looks after all the kids, but he takes a liking to Eleven.

He never explains what happened to 001.

(“Maybe we’ll save that story for another day.

It doesn’t have a happy ending, I’m afraid.")

Papa will allow it to happen, the orderly claims, because he’s scared of Eleven.

He reveals what looks to be a tracking machine implanted in his neck.

Realizing he had tremendous psychic power, he haunted his family with visions before ultimately killing most of them.

His father was framed for the murders and locked away in a mental hospital as a disturbed serial killer.

Henry then found himself in the care of Brenner, who decided he wanted more kids like the boy.

The young El faces Henry and, using a happy memory, overpowers him.

Episode 8 will be 1 hour and 25 minutes, while episode 9 will be nearly 2-and-a-half hours.

All signs point towards a rematch between Henry and Eleven, who now seemingly has her abilities back.

Will El be able to go two-for-two in the psychic ring?

We’d like to assume so, but it is the penultimate season.

Stay tuned for a full recap ofStranger Thingsseason 4, Volume I.
