Dante was just feeling grumpy in DMC2

A lot of people feel DMC2 doesn't work in the DMC timeline, because of how different Dante acts. In fact, he was just feeling grumpy that day for some unrelated reason. Maybe he had an argument with Trish or Lady back home because they took the last slice of pizza before he left. He got over it by the time he came back from hell.

Capcom wants to make another DMC 2 before making a good game

This is silly, but maybe Capcom makes DMC in cycles. DMC 1 was good, DMC 2 wasn't because they asked someone else to do it, DMC 3 was good again and DMC 4 was only half bad despite repeating levels and Nero, so they handed DMC 5 to another developer to make a game as good as DMC 2 and then they'll make a good one. Probably DMC 4 prequel about Dante, how Nero got his arm(perhaps because yamato was broken by him and Vergil's spirit that remained in the sword, possesed him?).

DMC2 Dante is actually post-DMC1 Vergil.

As far as This Troper could figure, it would mean that the third battle between Dante and Nelo Angelo ended in the latter's victory and the former's death; yet, just as Dante's memories were triggered after the fight, so did Nelo Angelo recall his past as Vergil. Defeating Mundus, Vergil assumed Dante's identity as penance, a trope not uncommon in fiction and particularly common in Japanese fiction.

DMC2 Dante is a drastic departure from the Dante seen in other games as well as the novels and manga; he rarely quips, and what he does say tends to be sardonic rather than sarcastic. His relatively no-nonsense approach to events are in contrast to Dante's typically-irreverent attitude; his abrupt transformation into The Stoic is startling, and hints of a more ambivalent persona - rigging the coin-toss, setting Arius up - meshes more with what we've seen of pre-Angelo Vergil than Dante's usual attitude. And, while admittedly a weak link, DMC2 Dante had an unlockable costume with a scarf, which seems to be a theme in Vergil's outfits: His standard outfit has a cravat, his Gilver persona has a scarf over his suit, and concept art for his design in 3 features a similar suit-and-scarf combo. Though DMC2 Dante uses firearms and broadswords rather than Vergil's katana and unarmed techniques, this is easily explained by the fact that both twins seem familiar with each other's styles, as seen during the Arkham fight in 3.

The reason why we never see anything more of Vergil-Dante is the timeline being reversed/undone; somehow, he undoes the critical fight on Mallet Island so that Nelo Angelo loses, Dante wins, and time flows in the manner we're familiar with. The 'why' is up in the air: Perhaps it was guilt at killing his brother, added to the humiliation of having lost to and served their father's greatest nemesis; perhaps it was an acknowledgement of his prior misdeeds, and admitting that Dante had/would make better use of his life than Vergil had. Alternately, maybe Hell - which Dante winds up trapped in at the end of 2 - is capable of tearing holes between times/dimensions as well as into the human world, and that enables Vergil to rewrite the past.

• Not mine, but it's the plot of this fancomic.

Lucia "defect" is this only from Arius POV.

She is able to more independent thoughts then her "sisters" and that's why she would make bad Secretarie. We never see her physically weaker than Secretaries of suffering from some ailments.

The gods of Vie de Marli granted Lucia sentience and powers

It has been hinted since the first game with the Divinity Statues that gods do exist in the DMC universe and 2's manual confirms this, describing the Protectors of Vie de Marli as people who can call upon the powers of their gods to aid them. If we go with the implication that Arius wiped out most of the Protectors, the gods decided to both give the Protectors a bit of hope and avenge their followers by turning Lucia against him, granting a free will of her own and divine powers that made her superior to the other creations of Arius.

Lucia can access a more powerful Devil Trigger if granted more power by the gods of Vie de Marli

Lucia's white feathers in Devil Trigger form are a sign of her being blessed by her pantheon. Whereas Dante's Devil Trigger evolves through Rebellion and Sparda, Lucia's could evolve by being more in touch with the divine entities her clan worships.
