Not sure if a spoiler but I will put it here to be safe.
Interview with Patrick which mentions a scene with Frakes where they are both digitally de-aged for what I assume will be a flashback.
RMB talks about flashback scenes and in an interview with Gates Mcfadden and Patrick Steward for Collider, Gates states that there is a "birthing sequence". So I think a couple of the Next Gen crew are going to be de-aged.

Since they thought about giving him hair, it must be before TNG. He had hair when Jack Sr. died...
Shaw is not a totally bad guy. He follows orders and is just dismissive of people, but doesn't break any rules.But the problem is, our heroes were part of Starfleet back then and they were there to right all those wrongs. At the end Starfleet are the good guys. Those hateful people were treated as fringes. However, now in Picard, our heroes are on the outside, retired or have no command. See how Shaw dressed them down, it’s like he has no respect for them (same for the admiral in season 1). It feels like this Starfleet and its officers are no longer the force of good it once was.
