Poseidon wasn't supposed to "wake up" and possess a host yet, but Kanon woke him up early. Kanon wanted to take advantage of Poseidon's power so he could rule the world, but before, in his cell, he realized Athena had been saving him each time he was about to drown (pfft even though Gold Saints can't drown), so just when Poseidon was about to stab Athena with his trident, Kanon blocked Athena and fell. He was later presumed dead. But as you can see, he was alive ;)
