Tegan and her duplicate clash over shared memory

Tegan and her alternate self engage in escalating verbal sparring over a trivial memory of childhood ice-cream, their playful rivalry exposing the unsettling reality of their shared essence. What begins as a test of individuality quickly reveals the futility of their conflict—the duplicate mirrors Tegan's thoughts with eerie precision, undermining the premise of opposition. The standoff forces both versions to confront their unavoidable interconnectedness, setting the stage for their eventual alliance against the external threat. Their unity becomes necessary as the telepathic species' exploitation of their bond with the dome’s flora grows clearer, revealing the true nature of their conflict as a distraction from a far greater danger. key_dialogue: [ TEGAN: Look, stop it.
