Perpetual third wheel

Poseidon's archnemesis is Pallas Athena. For winning Athens with an olive tree.
His most priced possesion is his trident.
And his power.

Athena is a college girl with a room mate strangely interested in Greek Mythology and a love for the ocean. So when she's swept under and find herself with Poseidon, it's just a weird dream, right. Right?
