In episode 2: worrying that he's going to keep mutating into a monster, Virgil stays after school and uses the science lab to compare his blood to Richie's under a microscope, but both of their blood samples look the same. But of course they look the same, because Richie is also a meta-human, he just doesn't know it yet.
Alternately, it's foreshadowing that the gas and the connected technology are the source of the powers, not unlocking something biological (so the blood and tissues of the metas don't look different). This is a distinction that defines most of the major differences in how the powers work compared to other superhero stories, something that the creators pay a surprising amount of attention to for a show targeted at children.
It just clicked: Episode 2 is about overcoming one's past with a bully, about not allowing the damage done to you make you feel less than who you've grown to be. The episode begins with Static facing off Hot Streak, only for the former to "choke", partly because he still thinks of himself as Virgil Hawkins up against his school bully Francis. Later on, before round 2, Richie has to remind him that his past as Francis' victim doesn't matter: in the here and now, he's Static Shock.
In "A League Of Their Own", Static is able to fly fast enough to stay ahead of the Flash. Static "flies" by using his powers over electromagnetism to levitate the metal disc he's standing on. The principles he's using to do this are the same ones used in railguns to launch a projectile to supersonic speeds.
It had been pointed out that most of the "Big-Bang Babies" use their powers for selfish reasons or downright villainy, with Virgil being among the few exceptions. The reason is the explosion's site; it was an industrial area, and late at night, with most of the people around being criminals (the explosion was partially caused because two gangs fighting) and poor people, some of them even being homeless. So, after getting their powers, they didn't see a chance to do good, but to enrich quickly, or, in the case of the most aggressive ones, to hurt people on a larger scale. Virgil, on the other hand, was already a good guy from the beginning, with a functional family and a stable income, and the only reason he was at the explosion site was because of being forced by one of the gang leaders.
In Kidnapped, Puff and Onyx question why Static is acting so dangerous when they just kidnapped one guy, Robert Hawkins, Static's father. Many fans have thought how dumb they are for not thinking it couldn't be Virgil. However, it's entirely possible that due to the episode Gear, Virgil was already kidnapped by Ebon for suspicion of being Static, but was fooled into believing he wasn't. The Meta Breed or someone probably spread the word about it and Puff and Onyx wouldn't think much of it either, they all live in the same city, every meta human would probably heard of it by now. For all they know, Mr. Hawkins is just someone important to Static, which is entirely possible too. Mr. Hawkins runs the Youth Center and he's always a welcoming man, the odds of someone like Mr. Hawkins influencing a teenager like Static is just all the more reason he'd be more serious looking for him.
In the episode "Now You See Him", Static is fighting Speedwarp, a villain who can accelerate time for himself and chosen targets. Towards the end, he kidnaps Daisy and accelerates her, and Static follows with his own time device a minute later. However, time is slowed down for Daisy and Speedwarp. Daisy must have been trapped in there for hours or days.
Wade was featured prominently in the first episode, but then was never seen or mentioned again after the Big Bang. While no fatalities are mentioned in show, we see a kid melting from the effects of the gas; it's likely Wade was one of the unlucky ones. This is most likely the case since in the comics, it was explicitly stated that more people died from the effects of the gas than were mutated.
The episode "Sons of the Fathers" focuses on racism, with the racist in question being Richie's father, who is pretty unstable in general. Now for those who don't know, Richie is gay in the actual comics, even if it's never fully addressed in the show but it's still somewhat canon via Word of Gay. This raises the question: Is his father the reason he's in the closet? While there's no solid proof that he's a homophobe, his racism and general unstableness before the episode's conclusion would probably be enough for Richie to keep quiet about his sexuality to his family.
Or at least a head-scratcher. By episode 21, Sharon is dating Adam, aka Rubberbandman aka a superhero. We see them together on a few dates with no implications they broke up during the whole rest of the series. Yet she's in danger in quite a few episodes, including kidnapped with her cell phone in one, and he never showed up in them. Not even a "I'm sorry I wasn't there but I'm glad you're safe" cameo. What gives?
The focus character of the series is Static himself; things happen outside of his frame of reference all the time. For instance, he'd apparently been constantly harassing his father to get back into the dating scene, but we don't find out about it until an actual girlfriend happens, aka when it starts impacting the protagonist's life directly. Fairly accurate teenagering there.
