Warning! Contains major spoilers for Constellation’s episodes 1, 2, and 3.
Constellation‘s big Alice mystery remains one of the most baffling elements of its storyline after episode 3, but the show’s casting choices might offer some answers to what it potentially means. Initially unfolding in the International Space Station, Apple TV+’s Constellation hooks viewers in its first arc by presenting a Gravity-esque subplot. Its main character, Jo, stays alone on the space station and races against time to fix it while her team members fly back to Earth after a disturbing accident.
However, after Jo completes her mission and returns to Earth, Constellation moves in a new direction, enticing viewers by offering bits and pieces of its overarching mystery but never wholly disclosing what is happening. During these moments, Jo not only notices how her surroundings on Earth seem significantly different from how she had left them but also sees another version of her daughter, Alice. Why she experiences these eerie occurrences remains uncertain, but the casting choice behind Alice hints at what the show’s big mystery could be about.

Who Is The Dead USSR Cosmonaut In Constellation?
After the first three episodes of Apple TV+’s Constellation, one mystery looms large: who was the dead USSR cosmonaut that caused the ISS accident?
Twins Are Playing Alice In Constellation
Two actresses, Davina and Rosie Coleman, who are twins, play Alice in Constellation. While twin actors appearing in the same show is not uncommon, what makes the Coleman sisters’ casting in Constellation intriguing is that they do not play twin sisters in the series. For the most part of Constellation‘s first three episodes, Davina and Rosie do not even seem to share the screen. Instead, in the show’s complex portrayal of space and time, they seem to be playing the same character, establishing a possible explanation for the show’s big mystery.

In Constellation‘s episode 3, Henry tries to explain quantum physics to Alice. To give her a simple explanation of quantum superposition, he asks her to imagine a particle that can simultaneously exist in multiple states. While the particle can be black in one world, it can be white in another. As Henry explains, the particle can also exist in a liminal space between the two worlds where it is both black and white and only decides what it is when someone observes it. Henry’s explanation seems to highlight why there are dual versions of nearly all characters in Constellation.
All the characters in Constellation seem to represent the particle Henry talks about. They exist in two alternate states in two alternate universes. For instance, Henry’s alternate version is Bud. However, Henry’s space experiment cracked the fabric of space and time and created a liminal universe where all the characters exhibit a form of duality. Therefore, like other characters, two versions of Alice exist. Like identical twins, they seem similar in appearance but are not exactly the same person, and Jo is even able to distinguish between them in Constellation through smell.
