Eve gives Rhea a 'special' kiss when she leaves since Rhea's the one who rescued her from the shopkeep. D'aww.
Iratu's insistence on "training" at the beginning of the comic could just be seen as a drunken romp. But why would he even think to do something like that, drunk or not? It's because the ascension to Medius requires certain standards of ability. The concept of training happens to Iratu while drunk because that's probably what he's been doing as of late, because he's a general in the ranks of hell and he knows he's going to Medius soon! The talk of training while drunk is just him letting it slip.
Some ominous dialogue from Sahne implies that ascending into Medius from Hell requires a mortal in some way (but apparently in such a way that the mortal can survive and ascend as well. Iratu made it to Medius, and he's allied with Mr. Moonshade, who's certainly evil enough to have been in Hell and thus have been available. Maybe Moonshade is the mortal that Iratu used to get into Medius?
Iratu is larger and stronger than other earth demons thanks to Darius's moon pendant and according to this comic Hell's Army works on Klingon Promotion, which makes perfect sense for how he is a General at only 27.
The majority of angels that were taken to Medius are caretakers (angel civilians basically) even though all they arrived randomly when they were sucked from heaven, the comics mentioned that there are relatively few demons and angels left because of the war. On the angels side the vast majority of casualties were probably warriors meaning there just wasn't that many to take.
Nikkei communicates via Signed Language (ASL to be specific) and she has five fingered hands however her girlfriend Hakka has Four-Fingered Hands and thus shouldn't be capable of sign language until you remember Medius is home to several race lacking five fingers so there is probably a unique dialect used by jakkai, khamega and fairies.
Cliff losing to demon Mook Haury despite the fact he was able to easily beat Denevol a seraph doesn't seem to make sense unless you think about it.
First of all Denevol while a seraph has been stuck on Medius for fifteen years and likely hasn't seen much combat in that time, this combined with his age left him somewhat rusty.
Their is also the fact that he and Cliff were friends before this point so he was likely holding back, something Haury would not do.
Also Cliff was clearly charging up a spell when Haury attacked, given the kind of environment most demons live in, alot of them would have a very pragmatic attitude in a fight and know to strike before they finish charging.
Finally, Cliff's biggest spell needs Duster's help in order to cast, and he likely wanted to conserve his energy just in case he needed it later.
Cliff's previous friendship with Denevol would explain his initially hostile behavior to Buwaro as Miranda says it's usually not like him to judge someone for their race, Denevol probably told him how his clan was wiped out and given his general attitude toward demons he likely didn't hear many good things about them. As this was his only exposure to demomkind before Buwaro this definitely colored his perception.
In an early strip, Iratu offers Buwaro some of his alcohol, but Death stops him. Later, Sakido mentions that Fire Demons explode if they drink. At first, this just seems like a bit of Alcohol-Induced Idiocy on Iratu's part (since he was drunk at the time), but after you learn a bit more about their past, you start to wonder if it was really unintentional... It becomes downplayed a bit when Buwaro gets ahold of some wine in the aftermath of St. Curtis and it merely causes him to belch flames. Still horrifying considering that most construction in Medius is wood, but at least not Ludicrous Gibs level.
In a later strip the Mixlings are revealed, which are cross-breeds between two Median races. Think about it... Then you realize angels and demons are also being added into the mix... There's also the fact that they have their own name for the many sub-species, along with the slang term "Bitza," suggesting Mixlings are actually a very common occurrence.
Does Darius actually know that Sakido is dead? He remarks that all of his children are "gone" from Hell when he's revealed to be Death, but that could also imply that he thinks Sakido made it to Medius instead. Just imagine thinking one of your kids is in a better place when in reality they've been deader than dead for a while now. Let's hope the truth isn't too hard for him to take if/when he finds out...
A blink-and-you'll-miss-it moment here, but while Kinako and Kieri are crying, one of the demons mentions that Lakritz "should be dead by now". By NOW. They straight-up left him there to slowly bleed to death after mortally wounding him.
Lazuli is a water demon (which are the smallest demon type) yet her berserk form is enormous, one can only imagine how massive a berserk earth demon would be!
It may be that it's not AS much of a change. Earth Demons may simply be bigger, but they don't change size as much when they berserk. Using elemental properties, Earth is the least flexible (water can swell tremendously, fire can grow with fuel, air expands considerably, but earth tends to stay the same size)
With the knowledge we now have on angels and demons both being a Dying Race thanks to the war and the fact they're both having difficulty producing offspring, this means that every angels and demon we've seen die is one step closer to extinction for both species.
