The Curse of Cabin 9 was introduced soon after Beckendorf's death. It was also intended to put a strain of Leo and how he felt like he was cursed all his life.

I dobut the Riordan would tap into that, but the whole Mimas appearing would make sense since, their are three people who haven't met a giant that is against their godly parent. So Frank needs to meet the bane of Mars, Piper needs to meet a bane of Aphrodite and Leo needs to meet Mimas in the end.

I would also like to see Leo go all out against Gaea since, she did mess with his childhood and we haven't seen him hold up any grudge, even alittle would be ok. Its his mother after all.
