I am thinking what if Theseus also attacks dawh. I doubt that he can be killed easily, provided he's in Tartarus. And it also eliminates the risk of Theseus accidentally killing Persephone. Just one more day and unless she was LIS or dies tonight, she will join us tomorrow. There's a good chance PT, AI or for that matter anyone other than dawh is Persephone. Dawh is probably an Achaean/ally(like Perseus), as no monster/ally would want to out Cerberus. And he's most probably a non-recruited Achaean or Perseus who wants the Achaeans to know that he's not a monster.
So what do you guys say to Theseus also attacking dawh?
