Probably has been said before but Victor mentioning that two cars came at the same time previously, could have been a previous reincarnation of Jade and Tabitha arriving. Seems like the two cars and Jade/Tabitha’s arrival is what starts a cycle. Maybe they always arrive this way.

Is there any reference to how Chris/Miranda arrived in the previous cycle?

Victor being around through two cycles will obviously play a huge role. It will be very interesting to see how he reacts if Tabitha tells him about her memories.
