As I recall, Jade was told by Karkat to kiss Dave; but that was a few hundred pages back, way back in the Doc Scratch thing, and I believe John and Jade met because time travel; John's package to Jade for her tenth birthday or so got sent back by PM to Jade at approximately half that. Again, I don't have a source, sorry. I don't think we know how the Derse kids met each other or the other two, other than that John was introduced to them by Jade.

So yeah, take this and cut and paste it together with the replies to that question as necessary.

Thanks guys.
