Yeah, yeah, Valgrace is Romeo and Juliet coded but hear me out: they’re actually Pyramus and Thisbe, which is a Roman myth.
Same basic story of rival families (rival camps, you know how those parallels work), but the way the deaths go down is different. It’s not a planned faked death that goes awry because the other person doesn’t know.
Pyramus and Thisbe plan to meet under a mulberry tree. Thisbe gets there first and sees a lioness killing something and hides, but loses her veil as she flees.
Pyramus never sees Thisbe’s body (because she isn’t dead), but finds her bloodied veil and assumes she died. He deals with this by falling on his own sword.
Thisbe returns, wanting to talk to Pyramus about what happened to her, and finds him dead/dying (depending on the version of the myth).
This is more accurate in terms of it being unintentional—Leo not wanting to fake his death but actively trying to escape death with his plan—Jason never seeing Leo’s body and the death by stabbing thing! It’s also perfect for Leo coming back at the end of Burning Maze and asking for Jason first thing and finding out he’s dead. You’re welcome :)
