Peter has no magic to null his way out of any of this, whoops, but he DOES have pretty good observational skillz and also likes to vlog things so he could probably figure out, hey, this dude keeps showing up. If he follows Eros to his mansion, could he find a way into the mansion from the rooftop?

He doesn't want to FIGHT A GOD, he's had enough of that kind of thing thank you so much, he just wants to talk. NO REALLY. Just be like "hey buddy look this is probably a lot of fun for you but I just had to lose the first girl I ever fell in love with and I'm fuckem tired please stop doing this, it's actually pretty painful" or something along those lines. /not in the holiday spirit, gj peter
