Even 2 years since Odysseus tortured Poseidon with his own trident; he was still bitter. But who wouldn't be? If some random Greek skum drugs your son, kills your sons only friends -who cares if they're sheep-, blinds your son, plays victim when you punish them, only to be tortured with your own weapon- you'd be upset to.

Hell! Even if he wanted to forget about it and move on he still has to see the scars everytime he's in the bath- like right now. Not only is he being a reminder of his defeat, someone just knocked on the door and interrupted his pity party.

"Occupied!" He was upset but tried to keep his tone gentle in case it was his son, Polyphemus- who was here in the temple to stay permanently (Poseidon is too protective to let him be on his own now).
