Summary
The entirety of existence itself seems to swirl relentlessly around him, the outside of his physical body mixing with the sensations within him. Years of diligent and dedicated self-improvement and growth collapsing in on itself with no fanfare.
He’s frozen.
Out of the corner of his eye, back in the mirror he sees it. An eye, all too familiar staring at him, through him.
That frightened child.

Summary
The Octonauts find themselves in strange waters. All the fish seeming to flee in fear. The waves strangely turbulent and unpredictable. A creature alert from a mysterious source, seemingly coming from a great chasm. It won't be too long till the fog above water finds its way down below.
This is a continue when I feel like it fic, so I apologise for any long breaks between chapters.

As Paani paddles down the Mississippi, he finds himself thinking about Kwazii. About his regrets, his wishes, and what-ifs.
The title and song lyrics used in the fic are from the song Never Love An Anchor by The Crane Wives.
This fic is entirely separate from my other Kwazii and Paani fics. Totally different. -
