Tentacle LordGenome is appropriately creepy, while anti-spiral Nia no longer has cheerful pastel colored eyes. (She kind of had an anti-magical-girl transformation too.) I'm still really liking the design of season two.
This episode crammed in a fair amount of exposition, really, without making it too obvious. Simon really should've kept an eye on Rossiu's brooding tendencies over the last seven years, but I suppose he's not that kind of boss. (And Rossiu was older to begin with, I guess.)
A good reason not to keep the same leader in wartime and peace, maybe - the older guy who just had a baby might have been a better choice.
