Three things -Courtney's met Wonder Woman before. Several times. In fact, they've had Thanksgiving dinner together. More than once. There're a couple of possible explanations here: Meltzer sees "teenaged girl hero" and writes her according to some kind of weird mental template; the script called for Cyclone, for whom the overly annoying dialogue would be entirely fitting, but Shane Davis screwed up; Stargirl's an idiot who repeats herself. I don't know how much time's gone by between the end of 52 and the beginning of JLofA (or JSofA, for that matter), but we haven't yet seen why Sand went from his GI Joe getup to this creepshow, aside from the obvious "Alex Ross freaking felt like it" explanation. Also, Christ, you think Brad Meltzer likes Geo-Force? God. Granted, the rate this series is going, it'll be another three issues before we see him use his powers again, so I guess the occasionally reminder that Geo-Force is even more powerful than ten Gokus isn't wholly without merit. Hey, I'd almost forgotten that these two were drug addicts at some point! Roy should totally toss in the fact that he had a kid with Chesire so we could cover the entirety of his character traits in one speech bubble. How come nobody ever calls Batman on that time he was hooked on Venom? It's always that one issue where Roy was on smack and beat the crap out of his addiction the old fashioned way - by sweating a lot in a room with Black Canary. Green Arrow could kick cocaine every freaking night, by that rationale.
Also, somebody explain to me how Miraclo is no longer a drug solely because it's not in pill form. Johns pulled the same thing roundabouts All-Stars - Hourman was all "it's homeopathic! It's transdermal!" which strikes me as about as logical as hooking myself up to a vodka IV and then claiming I'm not drinking because the booze ain't in my mouth.
