If you were going to pick a pseudonym that didn't stand out in any way what would you pick..
It's a pseudonym. All along JJ's been laughing at how he will give us just what everyone else in the STID story has as the movie opens, the name John Harrison. And by the end of the movie we and the characters in it will finally know who he really is.
I'll be boycotting the internet the day this comes out until I've seen it.
