invasion resolution possiblities

No it hasn't, and if you are going to pre-judge it before it even airs, why bother watching it.
They had to have some way to distinguish Isaac from all the other robots.

I'm sure everyone has thought the same thing. Most Orville watchers have seen just about every Trek iteration as well as other shows including the movie AI that deals in robot/organic relationships.

I added another scenario where the organic's bodies were buried in those caves simply because they killed *themselves* in a final war among themselves and the robots had nothing to do with it. Robots, not understanding sentiment, just dumped them there unceremoniously. The Kaylons however allowed the Orville crew to believe their story killing all the organics in some sort of a test. I dismissed that when the episode continued because it doesn't seem possible that the Kaylons would go to that level to test the humans.

I'm willing to go on a little faith and hope they end this (so far) excellent episode with a twist I haven't thought of - like an away team infiltrates the central command and initiates a reboot command (never mind, sounds like the "sleep" command that Picard suggested to Data about the Borg). Sigh..

They could use Isaac as a trojan horse to infect them with a virus of sorts.

Lame and boring? And I'll bet you'll watch the next episode...………...

I suspect that the resolution we got is a prelude to some sort of poor man's DS9 season-long war. I'm calling it now - there will be a time-travel episode where humans will witness how horribly bots were treated by their masters.
The resolution to the war will cause robots to understand how wrong they were in seeing all organics as being the same - bla bla bla - we are so sorry, etc.

Don't expect any sort of grey area here. Though admittedly, the reasons for the DS9 conflict were equally screwed up - and the resolution to that conflict was also fairy-tale like. The thing that DS9 did have going for it were fairly complex characters, sophisticated relationship between bajor and the federation, and a few other things which made things interesting.

I wonder if I'm just not into sci-fi for teens anymore.... at my age, I want complex characters, mature storylines, lots of grey area, rather than white and black - so yeah - I'm getting too old for this shit.

I think symbolically, they wanted to make Isaac stand out from the other Kaylons, and also to show that he wasn't entirely evil like them. The leader did point out that Isaac was not built until after the organic Kaylons had been massacred, so he had no experience seeing them enslave and abuse his robot kin.

I never really thought about the radiation problem on their planet. I'll have to watch "Identity: Part 1" again. It should be pointed out that we don't know the whole story behind the Kaylons, and the Prime could have been lying about the whole thing. Something else could have happened that caused the original inhabitants of Kaylon to die en masse, rather than having the robots exterminate all of them.

There is definitely room for more story involving them, particularly regarding those Kaylon ships that broke off and flew back to their homeworld. I have a feeling the Kaylons will be back to cause more trouble later.
