I agree with you, the reveals in both Weapon Lost and Adamantium Agenda were really underwhelming and just a confirmation of something we already suspected in the Hunt one shot. Let's hope Tamaki will suprise us with the last issue of Claws of a Killer, especially after the nice twist of the third issue.
I think the problem right now (for me at least), is how Taylor handled the reveal. The fact that Sarah used some parts of her DNA isn't problematic but that Laura is as much Sarah as she is Logan is not the same thing. I mean at this point if you've read ANW/Generations/Red annual it's basically Taylor just hammering home that Laura is Logan's daughter even if that was unneeded in my opinion because Logan already sees her as such.
As I said in my recap, maybe it will lead to interesting stories I don't know but after having witnessed what happened to Logan when some writers messed with his origin in order to overexplain or oversimplify things which in the end just turned him into another generic anti hero, well let's just say I'm a bit wary about what's going to happen to Laura in the future.
Now that's a reveal that would "bend" the internet lol.
Love all those theories you guys came up with, keep them coming!
So looking at the list of suspects: Colossus, Nightcrawler, Rogue, Jubilee, Storm and Kitty should be safe. No way they will retcon any of them as non mutant.
About Doop, he's not a mutant, he was created during WWII, he has lot of connections with the underworld and he was the guardian of the JGS but beyond that we know nothing about him. His last words to Logan were really strange.
Firestar, okay she was never close to Logan but she joined the Amazing X-Men team some time before Logan's death. She disappeared when the Hunt was started but she was recently part of Emma Frost team during Secret Empire. Maybe she has something to do with Logan's hot claws!
Cyclops, well he's dead so I'm not sure if he's involved in this thing and honestly I don't think Marvel would retcon him as a non mutant. But Cebulski teased something regarding the Hunt : "And if I can drop one hint: was Vulcan the true third Summers brother?!" So maybe it's just some tongue in cheeks comment but what if someone from the Summers family is involved?!
Beast, so good ol' Beast let's say that he could be another interesting suspect. He was the one who evoke the possiblity of an X-Traitor, his actions in recent years have been really questionable and he already experimented on himself in the past. Also he's the one who diagnosed Logan as "dead". What if it was a lie?
And finally the the last suspect Logan himself!? Yes what if Logan was never a mutant to begin with and always a sleeper agent!
If you remember Uncanny X-Men vol.1 #98, Stephen Lang found out that Logan was not a mutant but something else (he was supposed to be a mutated Wolverine but it was quickly forgotten).
Also thanks to the horrendous X-Men Legacy/Wolverine Origins "Original sin" crossover by Mike Carey and Daniel Way we know that Logan joined the X-Men in order to kill Xavier so he was a sleeper agent for Romulus (another idea that should have been forgotten). Now of course it wouldn't make a lot of sense but who knows lol.
Also there is the possibility that a doppelganger replaced one of the X-Men, the same way a skrull that impersonated wolverine infiltrated the X-Men before the Apocalypse the Twelve crossover while the real Logan became the Horseman of Death. If that's the case, the question would be to know when the switch happened and if one of the suspect has been acting strangely in recent years.
By the way, maybe I missed something but why was this mini entitled Adamantium Agenda? Why did the sollicitations tease a metalurgic miracle?
