I actually think Percy and Will would get along perfectly well. Like their chemistry would be on fire, and they would just click. Because their characters are actually very similar, the way they both had to take on a big responsibility at a young age, because no one else could, and also they wouldn't let the others to carry the burden either (Percy taking the weight of the prophecy on himself because he didn't want Nico to carry the burden after Thalia became a hunter and Will taking the weight of being the counsellor and the sole medic of the camp so that his younger siblings would not have to after his older brothers died in the battle.).
They both have a golden retriever energy, but inside they both have heavy suppressed trauma they hide behind the mask that 'everything is fine' and both of them are five seconds away from a crashout. If you cross a line, they both flip out and have an angry episode. Also they are both overly protective over their significant others (wink wink). They both are their father's favorites and they both have a good relationship with their mothers.
They both fell in love with someone who other people perceived as scary and hard to manage. And they both didn't hesitate to follow them to Tartarus.
Also they are the hottest two men in the camp lol. Just look how Will is described in Tower of Nero when he was taking his shirt off. Also his father is Apollo, aka the hottest god ever. We already know Percy's levels of attractiveness.
Besides I really don't think Will blames Percy for what happened to Michael. That being said, Will and Percy would get along a lot better than Will-Annabeth or Nico-Percy dynamics. And Nico and Annabeth would also get along better too.
Meaning they should start going to double dates AS SOON AS POSSIBLE. Thank you for the ted talk.
