Silly Jonelias scenario I am currently rotating in my head:

Post-Canon Jon travels back in time or to some alternate universe, where he meets past/alternate version of Jonah, who (naturally) becomes obsessed with him; Jon eventually warms up to this Jonah, who hasn’t really done anything too terrible (yet)… and is pretty much his soulmate, unfortunately.

But then!!! Post-canon Elias follows him Also (because he wants revenge, or whatever). And gets Extremely Jealous?? Because how dare this Jonah try to steal away his favourite toy???

Anyhow, Elias and Jonah get into an extremely embarrassing cat fight.

Jon just wants a nap.
