Follow Your Passion: A Seamless Tumblr Journey
I have to say that PJO as a fanbase can be surprisingly biased against Calypso and sometimes their misogyny shows. You have a right to dislike Calypso and how she was written and retconned, but some of the posts I've seen about her are just plain misogynistic.
Calypso doesn't owe her life to Leo just because he rescued her from her island. She doesn't have to cater to him and his desires. She's entitled to live her own life on her own terms.
If she wants to stay back at her school instead of spending time with Leo, if she wants to travel the world with or without him, if she wants to make new friends and hang out with them, she is entitled to all of that and she's not morally bad for it.
Not to disappoint Caleo shippers or anything, but I honestly think that the best arc for Caleo would be for them to break up. Calypso wants to travel the world and make new friends; Leo wants to stay at the Waystation, teach kids and help them. The natural solution? A breakup. It doesn't even have to be messy and sad either-just a simple, amicable breakup, an acknowledgment that they like each other as friends, but that they can't stay together because they just don't work out.
I also think that this breakup arc would be healthy for young children and teenagers who read this because it shows them that not all breakups have to be messy and sad. That you can breakup with someone politely and remain on good terms with them, which makes the readers less apprehensive about breakups.
Just my thoughts, feel free to add on.
