(MAJOR SPOILER ALERT)
Okay, so in the movie, Wolverine, Hank, and Charles recruit Quicksilver to help them bust Magneto out of the Pentagon cell. Hank and Charles explain the cell to Wolverine, and Wolvie is like, "I know a guy who can help us." But! Why does Wolverine know Quicksilver in the first place, specially since this is the first time he's been in an X-Men movie? This is really bugging me. The only reason I bring this up is that I was revisiting a thread that came up during my gay superhero post from last week, and someone pointed out that they could have used Northstar instead of Quicksilver, especially since a. Quicksilver's parentage wasn't explicitly mentioned (did anyone else catch the exchange between Magneto and Quicksilver in the Pentagon elevator?) and b. they didn't even bother to include Wanda as his twin. I'm probably overanalyzing this, but I think it's kind of unfortunate Quicksilver is both in X-Men and The Avengers, and his story has to altered in both to accommodate all of the stupid copyright bullshit* between Marvel Studios and Fox.
*Yeah, yeah, I understand why Marvel had to sell off the rights to X-Men, but still.
