Are the Tethered shadows, mirrors, or clones of their above-ground counterparts?
Adelaide has literally been wearing a mask her entire life, living a stolen existence.

Just before the Wilsons are attacked by the Tethered, Adelaide’s spidey senses are tingling.
“I think you look like yourself,” he replies to her.
And that is because she knows that she’s in the place she’s not meant to be.

“I feel the girl is getting closer,” she says… And that would be the impact of Adelaide being locked underground and not speaking for years.
Either way, Adelaide/Red wants to keep him close.
In present day, the attraction is renamed “Merlin’s Forest.”

The May 25, 1986, charity stunt Hands Across America is a recurring image throughoutUs.
So what does it mean when the Tethered adopt it?
A New Dawn
There’s also something to be gleaned from the names of the Wilsons' doppelgangers.

Universal Pictures
Gabe’s Tethered self is called Abraham, a Biblical patriarch known for his devotion and loyalty to God.
Red’s children also have intriguing names.
It is interesting that Jason’s doppelganger is given such a prestigious name.
