being a smarmy, glad-handing, brown-nosing, corporate jargon addict? That feels like a pretty crappy downside to super-strength.
I've been thinking about Daisy's eye makeup since the end of last season. There's a concept in the hacking world called "facial recognition dazzle" that takes the concept of dazzle (painting warships with high contrast, jagged lines as camouflage -- it worked really well before radar) that uses makeup and hair styles and some shapes of hats to confound the algorithms used to ID faces on surveillance cameras. In the real world, the makeup and hair are so far outside even avant garde/punk/extreme fashion that wearing the dazzle makes the wearer more likely to be noticed by humans, and thus defeats the purpose. The cameras might not catch you, but everyone you passed will remember. However, they've been trying to refine it, and one of the things heavy eyeliner and strong contouring can do is to change the match. If your file photo has natural makeup plus the dark circles under your eyes concealed, then wearing high fashion, high contour makeup with a heavy smoky eye and the dark circles emphasized will confuse the match. Which Hacker Skye would have known, or could have looked up, especially because she knows SHIELD's social media image scraping software. But the makeup artists for the show can't do actual facial recognition dazzle, because it doesn't make sense of you don't know the context, so Panda eyes/skate-punk was the compromise.
On the ghosts: oh god, I hope this story wraps soon. I can deal with gross, mind control, parasites, vampires, werewolves, zombies, traitors, Hydra-Nazis, but ghosts are the thing that freaks me out -- they screw with the observer's sense of reality, make people think they're going crazy, don't necessarily have much physical power (though these seem to have some ability to interact with the world, at least near the reactor/cubes) but also there's no established way to get rid of them and these don't seem place-bound. (I know ghosts aren't real. Doesn't mean the idea of them doesn't make my skin crawl.)
Hive as Satan vs everyone else who claimed the title: humans have a deep mythos about an ultimate, embodied evil that is cross-cultural, transcends religions and keeps enduring. Pretty much any creature who wants domination, destruction, mass enslavement, blood sacrifice, etc and who has done even a little bit of homework is going to play to that mythos. They were probably all at Woodstock, too.
