>We know OG Morpho and Jonas Sr. were orgy buddies
>Thanks to the Dr. Quymn episode we also know that Jonas, even in his later years, enjoyed the occasional swingers party
>Maybe Jonas and Morpho found out one day that a booze-and-more-fueled night of depravity they enjoyed a few weeks/months prior and can barely recollect, resulted in two bundles of joy
>Having no idea who's the father of which child, they draw lots for them, of play Rock, Paper, Scissors or something
>Years pass
>Jonas is more popular than ever thanks to the Rusty Venture Show
>Meanwhile, Blue Morpho is all but forgotten, since his comic series tanked after six issues, and is stuck with a good-for-nothing L'il Monarch
>Jealous, he performs some DNA tests
>He finds out Rusty and Monarch are half-brothers (which would explain how god-gassed Billy mistook Blue Morpho Junior for Venture)
>And Blue Morpho is the father
>He wants to take Rusty from Jonas to bust his own popularity
>He even kidnaps Rusty
>Jonas sends Kano after him
>Seeing his former(?) boss so unhinged, Kano is forced to kill him
>he takes a vow of silence as a sign of mourning
>Rusty forgets all about it, because it's same shit, different day for him
>L'il Monarch, who was brought along for the kidnapping, represses all memories of the events, but subconsciously remembers that it had something to so with Rusty
>And so, a lifelong vendetta is born
