One thing I respect about this show is that it can be off the air for two years and the first episode back feels like it aired the week after the last episode. No big fanfare. Not much/any catch up (which is remarkable considering how deep the mythology goes). They jump right into it.
You watch last night's ep yet? Quality isn't going anywhere. Still on top of their game, and I think they have plenty of mileage in this story yet, based on all the shit they dragged up in the first three eps of this season alone.
Well with that season finale, along with another revelation earlier in the season I think down the line,
Rusty and the Monarch are related, but Jonas isn't their father. Monarch was artificial insemination of the Blue Morpho. Rusty was intended to be a clone of the Blue Morpho, that would have been the underling/companion of the actual clone of Jonas, Jonas Venture Jr.
The Helper bot revealed this season Rusty was a clone. People think like Hank and Dean being re-cloned all the time, but I find that hard to believe as Rusty has great memory of his youth, while the re-cloned Hank and Dean had no memory of a good chunk of their childhoods. Then when Jonas Sr. was shown this season he wanted to clone himself a new body ASAP, which evidences he made the cloning tech to make Rusty.
Also, James Urbinak voices both the Blue Morpho and Rusty, even though half the cast is Jackson and Doc, the voice similarity is really noticeable.
