In the upcoming season 9 episode "Field of Dreams", we see Morty passing through his family mourning him through VR sets.
He looks puzzled (or... cautious) as he passes through them.
Everyone is reacting differently. Beth and Summer want to hug someone, Rick drinks (HAHA), Jerry... mowns the lawn?!
It's unclear whether MORTY is the one who set them up. Could it be they have not realized this is all happening in a different dimension?? (Even Rick??? Did he do it and forget??) Did Morty do this to make them appreciate him more?
But then, Morty goes on to use a portal gun straight afterwards, ALONE. Did he set this up to distract them while he is strolling through dimensions? Is he tip-toing among them so he can sneak away?
Or did they do this to themselves accidentally as they spent time looking at other dimensions, and they got caught up in the feels?
Or this is all happening to a different family? Did THEIR Morty set this up? Is THEIR Morty truly gone, either ran away or dead, and having no body to say goodbye to, they do it through another dimension's funeral? (weird that whichever Rick lives this did not replace Morty with a clone. Could this have something to do with the gene lock placed on Morty Clones? Are most surviving Mortys in the multiverse unclonable?)
Are these random birds, or are they crows???
Did Morty wonder into a dimension where he was permanantly replaced by crows???
...Is Morty wondering through dimensions where he is, in one way or another, gone?
Of course, there are a million possible explanations for the above scenes. Morty is sneaking away to meet a bird gal, it's all an elaborate prank, this is just a bit, whatever.
If my theories about Puppetloser Rick's (aka the Rick responsible for the cables inside Eyepatch Morty's head) existence are correct...
I had hypothesized he would need to scan the multiverse in order to find his old sidekick, for which he might have needed the lock placed on the Morty clones cracked. Unable to do so himself (cause he's a LOSER), I had supposed he sent a puppet to prowl around the Citadel's ruins until someone more skilled than him achieved this feat, with him speeding the process by providing... ergh... fresh material.
When that proved fruitless (because everything exploded), I had hypothesized he would need the one true Morty, the Morty whose copy all clone Mortys are, who probably doesn't have any gene lock on him...
...AND WHO MIGHT BE MORTY PRIME.
I had hypothesized one of the ways he could get access to Morty Prime's brainwaves would be to lure him out of his dimension and his Rick's "protection" and straight into a trap (see points 4 and 7 here. Strangely, point 7 included an alternate reality VR set, although I had imagined a different use for it)
And here in "Field of Dreams" we (maybe) have Morty Prime wondering through dimensions without Morty, ALONE.
You know what, I got excited at first, but Morty does not seem to be in much of a hurry in this scene. I have trouble seeing this as the result as someone's intentional lure. I could be wrong about everything, or Puppetloser-related plot might get advanced in a different way.
Edit 2: I just realised that in this "Field of Dreams" we may be witnessing point 9 of my Puppetloser Rick Is Hunting Eyepatch Morty theory: Puppetloser Rick brute-forcing his search through the multiverse by attacking every Morty he can find. If we come across an inordinate number of Mortys dead or missing...
...that could be Puppetloser Rick's doing.
And Morty Prime could stumble on him by accident, right when he's slicing some Morty's head open.
