Peleus didn't know how he'd ended up crashing into this party which was literally boiling over with immortal vibes. Maybe that had been the attraction, hoping above all hope that he might run into someone who didn't want to wage a war on him. He'd yet to speak to his son or to his wife who still shunned him as the day they'd first split. He was still sticking to his guns in this giant custody battle they'd come into over Achilles, he might always fight it til the day he died...again.
He had dressed in something fitting that he could use to cloak his face in case he needed to make a mad exit. This place felt full of trouble, but the ex-Argonaut just tested the waters. He'd feel it out before deciding if he couldn't handle it. He even had a sword.
