I'm not a fan of either of them. Solangleo was fine in heroes of olympus but feels forced in trails of apollo. In trails of Apollo I feel like it only exist for Rick to tell people he's ok with gay people. Jercy honestly would have felt better more natural and they are both straight. Likewise I feel like most people only make a big deal out of solagelo because it's a canon gay ship.
None of them. Rick needs to stop with the gender-fluid Alex and homo Nico. KIDS read these books! Some people I know have stopped reading his books after Nico's homosexual problem. It's against my personal biblical ethics.
I'm a devout Christian and a kid by some people's standards (including my own), and nothing makes me happier than seeing kids exposed to LGBTQ+ folks. Kids need to see people like that and know that they're normal. Some kids are like that themselves and deserve to see that they're accepted in this society.
