Alternate Character Interpretation: Is Clive a tortured soul who did what he did because he saw it as the only solution, or an entitled brat who wanted to see the world suffer the same cruel fate that he did just so he could feel better about it?
Inferred Holocaust: A giant mecha bursts through an underground cavern and high above London, then proceeds to shoot at will on the city. Thousands presumably die. Then the same mecha falls through the hole it created and explodes in mid-air, completely incinerating the fake London underneath it, but apparently having no further effect on the city above, despite it actually being closer.
It could also be inferred that the attack on London cripples the UK as a whole and leads to more chaos around the world. Since most of the world just saw a quarter of London get obliterated by a WMD, it's entirely possible that other superpowers (Like the Soviet Union) took inspiration from the attack and made similar weapons of their own...
The Scrappy: Bill Hawks. The guy is essentially responsible for most of the game's conflict, exemplifying the trope Sleazy Politician that most people usually hate, yet you spend much of the game trying to rescue the bastard. And yet Clive somehow lets him get away with it, too!Also, he's ugly. He's particularly a popular Acceptable Target amongst the Top Ten List community. Then again, he may have been an intentional Hate Sink right from the start; it's hard to tell. But even then, a Hate Sink is supposed to ultimately suffer for the audience's catharsis — something which Hawks avoids, therefore just being an unpleasant source of burnout.
Ships That Pass in the Night: Flora and Clive. The ship potential is there, but they don't interact much unless you count Clive kidnapping Flora.
