OH GENTLE READERS POSSIBLE SPOILERS; DARE NOT VENTURE HERE
Laurie filling a slot - and/or Laurie & Janey just being interchangeable objects, which then opens up a nice presentation into probably how Jon feels about all humans all the time, right? Which would make sense for why he decided to save the earth - one human equals all humans, and so on (although to be honest it seems like it's on a whim and not really because of Laurie at all, just "oh you're so special i'm going to make this seem like it's about you"). Is this spoilers? Am I getting ahead of myself here? I don't know where we were supposed to stop.
Doctor Manhattan isn't John Osterman
I could keep drawing Swamp Thing parallels here, except I think everyone else would get bored with me. The Swamp Thing isn't Alec Holland either and that's something he seems to grapple with pretty constantly - while on the meantime, it doesn't seem to bother Jon at all that Jon is no longer human/who he used to be. I mean, (Swamp Thing Spoilers) ST went and dug up the skeleton of his old body and gave it a burial, as opposed to Jon who didn't have a body left behind and just reconstructed one out of air and his powerfulpowerful consciousness.
I have always thought Superman was just plain old boring because he is just so vanilla plain-jane good, but I have never read the comics on him himself, just seen the videos and live-action comics and suchlike.
