Shower begins with Amanda and Brittany drifting through foggy thoughts and memories. They are unsure what is dream and what is real. The listener is pulled into the same space of uncertainty, except for one undeniable detail: the tentacles are very, very real.

What follows is a sequence of rituals and revelations that tie their personal disorientation to a wider pattern. Myths of brides of the sea return like half-remembered lullabies. Forgotten gods and rituals of cleansing surface in ordinary spaces, transforming the simple act of bathing into something sacred and unsettling.

Elsewhere, Sarah and Kara stumble across fragments of hidden lore. They piece together ceremonies of binding and trace the shape of a looming figure known only as the Old Groom. Each discovery suggests that the voyage is less about travel and more about surrender to forces that have always been waiting beneath the surface.

By the end of the episode, Shower makes clear that this is not renewal but erasure. Memory and identity are stripped away, leaving the crew caught between comfort in forgetting and terror in understanding what they have become.
