Paul you're pretty much right about Deathstrike in the comics. My friends and I were wondering if they would use the comic storyline with them, but they obviously didn't, even though Logan does have amnesia. I thought there would be some sort of recognition in his face in the fight scene.

The movie universe is different and the movie doesn't have to be exactly like the comics. Also, like you pointed out, she wasn't a major player in the story of the movie anyway, only in Logan's past in the comics.
