Could've sworn I saw some "news footage" showing Michael Jackson stepping out of an ambulance and being secreted into some building, hehehehe. It was hilarious because "Michael" was carrying an umbrella and wearing a mask -- usually we'd say it was needed to obscure the person posing as Michael Jackson, but that was completely normal for him in the first place.
I haven't read the musings on "abovetopsecret" yet, but is it possible that a celebrity reappearing could help prove Time Bastard? Like, if Michael time traveled in another dimension, he'd Gate into the new timeline, even if he had died in this new timeline. Or...something?
