It's not the Helios is stupid or anything- I mean he is but think of it from him pov
He really loves Diana, he doesn't know about her trynna seduce Kael so he's clueless about her- he still loves Diana and is trying to prove that to Diana herself
Even if she's a horrible person he doesn't see it that way since he always knew her as a kind person and nothing else
Still I hope that Hess really bitch slaps the both of them
