“On my Earth, Echo was a failed audiophile. She lost her hearing in a lab accident. She doesn’t want noise. She wants the absence of error . Lossless. Perfect. Unforgiving.”

Back at the lab, Barry can hear again, but he’s shaken. Echo’s power isn’t just sonic—it’s psychological. Lossless silence triggers sensory deprivation panic.

Barry arrives. The cube activates. Silence.
