For quick review, I go back & forth on 3 or 2.5 of 5.
Love Rectangle
Logan, Scott, Emma, and Jean are getting along well. Which is fishy and does bring up some possibility to Sinister Secret #5 for them. Polyamory or equal cheating. lol.
Cameos
Nice to have it confirmed that Skin & Synch are back. It's too bad Monet was left out given her romantic history with Synch. You'd think they'd have gone to the celebration together.
On Sabretooth
Narrative wise it makes sense for Hickman to get rid of him given the character has become rather useless over the years. While Hickman didn't do him any justice, he at least euthanized him to keep him off the table until something interesting or good can be done, which it may take to write him out of this,
In-story wise it makes sense given the way he's been written as a villain the last few years. He has no sense of subtly and simply can't cooperate or even pretend to like his smarter self from the 90's. He's a meathead and liability in any situation, so there's no point keeping him around. The flaw however was execution. Magneto sends him on a mission he had no business on just to punish him when he does the only thing he is good for these days, lol Unless it was a not-so-subtle way to get rid of him.
Also, now some can finally stop complaining about him getting off free. I think it was obvious he'd be punished for his crimes. Unlike Mystique, he doesn't get away with anything (everything in her case). It was only a matter of time. And clear it was gonna be lasting when he's been absent from anything related to DOX.
