Hollyyyyyy shit, if Snoke is the canon Luuke that’s insane. I just saw a reddit comment I really liked regarding this:

I was just thinking it kind of deepens the idea that Kylo is trapped by the Skywalker legacy even when he ran away after the Temple incident. It would mean he unwittingly traded a flawed but well-meaning Luke for the openly manipulative and abusive Luuke, and Snoke is all the worst things about Luke that Kylo saw or imagined, so the “true enemy” line and continued build-up of hatred towards Luke could hit a little harder (especially if we ever find out that Kylo learns of this from Palpatine on Exegol in a parallel to this comic scene).
