AMPHITRITE didn’t want to know and zoomed off on a tidal wave to the Atlas Mountains in Africa, possibly having a small collision with Atlantis on the way. ("Yes officer, there was a slight bump — I thought it was a speed hump or something.")
POSEIDON didn’t chase her but sent Delphinus, King of the Dolphins, to charm her. And well, who can resist dolphins? Certainly not a Sea Goddess. So she swam with the dolphins back to POSEIDON and they were married.
The romance soon went out the window because POSEIDON is such a louse and a cheat. This causes AMPHITRITE to lash herself into furious rages which cause storms at sea.
P.S. Under the Romans she changed her name to SALACIA.
