That is okay. Really all you need to know is that Jason is from the sequel series where we find out that there is also a Roman demigod camp, there's a giant world ending prophecy, and the Romans and Greeks have to come together to stop the world from ending. Demigod hijinks, monster fights, and various other events ensue.

Jason is the child of Jupiter, so his main powersets are wind and lightning. He can also fly...but not so well now that he is here which makes him a little grumpy.

But, yes, CR is going to be very fun 8D I love getting Jason involved with the other younger people in game. He's already pretty much become bros with Steve and he had a brief conversation with Nancy, so I'm just going to keep collecting Stranger Things fam.
