While this sounds interesting, I hope not because it's too retconny. Besides, Q told Picard he needed to be forgiven and when Picard asked for what, he was told, "I think you know."My theory:
Q saved Picard from blowing himself up, and thus Q(!!) broke the timeline (and that's why he's sick) - and he's sending Picard on a journey to fix the timeline as a quid pro quo.
So why does saving/blowing up Picard messes up the timeline? Because the Borg Queen is his mother ("look up Picard" - shoutout to superstar Rich Evans from redlettermedia who first proposed this idea), perhaps a variant sent back in time to the farm where she tells little Picard to look in the Stars for her (future/past version) while also fighting the Borg monster (herself) in the cellar. And Dr. Soong (the one from 2024) is therefore of course his father, and the whole thing is about "family" (Vin Diesel grunt)![]()
I do think Q wants to help him though. He did say he wouldn't let him "do it alone".
Would be interesting if the creators reference COVID-19 through having Q be sick because of what he did to save Picard et al. The universe/time pushed back at him perhaps...
