Hey, thank you! I don't think it'll play out like this in canon but I like playing off riffs, splashing around in 'au's' as it were, and I'm happy you think it would be a powerful ending.

Astrid would definitely get promoted *g*, as for Robert, if Olivia has to die in all realities, then this is a return to blue-verse after her death, where Lincoln (possibly) wasn't partnered with Robert to begin with.

Different universe to amber - so different events - not partnered with Lincoln, Robert never chased a shady man into a warehouse, never died, etc, etc.

I'm actually thinking about expanding this story - but I could do a red/verse resolution if you preferred.
