I imagine this post might make me sound arrogant.
Sad Panda is sad.
"s' " is solely for plural-possessive usage. The "s" does not denote more than one "Leonida;" the letter is part of the proper noun.
Superman: "It's not an --"
Femtech: "THIS ONE IS AN 'S'!"
Superman: "..."
Femtech: "..."
Superman: "Where I come from..."
Femtech: "AAAAH!"
"Leonidas" is singular, so "Leonidas's" is the only correct way to literarily convey the-man-to-whom-the-name-belongs's ownership of something (see what I did there?). Any other way of writing it is entirely attributable to the seduction of popular misusage. This is akin to how too many people say, for example, "there's problems" instead of "there're problems."
Or: "SDCC 2013 -- it's going to rock" instead of "SDCC 2013 is going to rock."
The term, "plot," refers to that which you see and hear in a film. When one refers to eye candy or whatnot, she is, by definition (though not necessarily by practice unfortunately) referring to plot. The thematic material, suggestions, and general intangibles as derived from what you see and hear are categorized as elements of "story." To streamline it: "story" refers to that which encompasses the "plot" and everything that the plot infers.
Barry, your point about TT is interesting. I haven't read any of the New 52 comics; admittedly, the last mainstay DC issue I read was something from Blackest Night. ^_^" What was the justification for Kal's flight capability in MoS? Your explanation of TT sounds good, but would Goyer really attribute the means of flight to something non-comic readers wouldn't be even remotely privy to? I remember a VO from Jor saying something along the lines of Earth's gravity being weaker than Krypton's or something, but that hardly equates to flight capability. Was Kal's mid-air pushing with his freak strength what was doing it, like a double jump in Super Smash Bros?
