It wasn't like he was in the clear of ever being a target from her. He was still her philandering husbands bastard. Usually the Greek women frowned upon those that weren't their own. Even though they'd had a rather touching moment in conversation months ago, it didn't mean she wouldn't kill him just for the pleasure of pissing Poseidon off.
