He is distinctly Iceman and not the Silver Surfer.

In the old days... "For the team of mutant superheroes known as the X-men, a busy week has become even more so..." would have been followed by an entire page recapping everything from the battle with the Sentinels to Dark Phoenix. Which made me realize how much real estate those pages used to take up in traditional comics. 

If traditional comics had been delivered to us online — one page everyday of the month — I doubt "flashbacks" would have ever existed. 

I never cared much for them, because I was a loyal reader and didn't need a summary of what happened in the previous issue. Yet, as a kid, I understood their purpose and found them useful when I was new to a comic — like when X-men #138, was my second introductory issue into the mutant's universe. 

As to today - I love Scott instantly figuring out the metal thing isn't Magneto due to how Magneto joins metal together.  Makes perfect sense that he'd know how to recognize Magneto's work from others much like recognizing one artists' work from another.  Lots of fun to read - glad also to know the smudge on the page was just that, an accidental smudge and not a hint of anything.  We fans all go way to much into these small things at times :)
