First, that was Stryker's dad in First Class. Second, I addressed the age thing in the post you quoted (check the last sentence). Yeah Stryker is old in the X-2 flash backs, slightly younger in Origins and a lot younger in DOFP. Mainly there is no plot hole with Wolverine's origins because he goes back before he ever meets Stryker that was my main point so there is no reason to say there is a plot hole there it works time wise for the events. The inconsistent age thing is annoying though.
To me, the events of DOFP could have changed everything. With STryker now VERY aware of Logan and his abilities apparently before meeting Logan.
Maybe now they could do the Weapon X storyline the right way, where Logan is specifically targeted, kidnapped and experimented on.
Also, I find it hard to believe that Logan met Origins Stryker in 1973. Stryker tells Logan it's been 6 years since they last saw each other. If three mile incident took place in 1979, sure that's 1973.... but I find it hard too believe that Logan, who in DOFP 1973 showed no signs of being a vet, on leave or currently in the war (no tags, etc).... joined the army, went through training, was sent to Vietnam with his brother, then was picked up by Stryker in Vietnam, became an integrated member of the team and abandoned them all in less than a year.
DOFP also does not at all hint that Stryker is in the works etc to create his own mutant team.... as it seems he just works for Trask through a military contract. By no means does he come off as the knowledgable, mutant manipulator with a mutant son that we see in Origins (1973?)
Also, in Wiki.... it states that Logan met Stryker in 1975... not sure where they got that date from or if its official.
But with the inconsistencies between ALL the movies especially in regards to X2 to Origins to DOFP...... who knows?
Again, I think DOFP could have changed everything, making X1, X2 and X3, half of Origins and especially "The Wolverine" possibly no longer in existence.
Apocalypse is to be set with the FC cast and maybe Jackman as Wolverine...... so I'm betting it'll be set in the 80s, probably changing the established Xmen series even more...
They seem reticent to place McAvoy entirely in the chair, and of course shaving his head. I wonder how long they can continue to make excuses and prolong his "Patrick Stewart" phase.
ALL that being said - I'm loving Logan's style in DOFP. Funny enough, even my wife took note and said, "He dresses like you!"
