- Archangel Gabriel: Mostly For the Funnyz. The mental image of a Serafall being jealous/annoyed/incredulous at her rival "goody twelve-wings Gabriel" becoming a love rival is funny enough to picture on its own, but if you add the rest of The Great Seraphim (Uriel, Raphael, and super Nice Guy Michael) acting as a Knight Templar Big Brother to their ingenue and something of The Ditz sister and threatening Harry to go (literally) full Old Testament on his ass if he ever does anything to hurt her or make her a Fallen Angel, plus Azazel and Lash plotting to bring about that exact outcome, and the rest of the world having the Entertainingly Wrong idea that Harry was helping the Angels with their Can't Have Sex, Ever problems simply because he wanted to tap that from the very beginning, it becomes a SNAFU worthy of Harry Cosmic Plaything Dresden — Andrzej
- The Christmas Episode showed that Lash can remote-control illusions of her preferred appearance like one would with a videogame Player Character.
- Right after the Kyoto School Trip Story Arc, DxD!Lasciel demonstrated a complex magical technique that can create a soulless homunculus from a person's DNA sample in a matter of minutes.
- The Alice White Rescue Arc confirmed that Lash possesses her own soul distinct from Harry's.
- Finally, Harry can imbue objects with his own soul, as seen when he tried to use Soulfire to scan Sona, Reya and Tsubasa's Evil Pieces (and accidentally getting them to undergo Mutation as a side-effect).
Putting all this together, it could be possible for Harry to put a piece of Lash's soul into a custom-made homunculus based on DxD!Lasciel's own DNA, which could allow her to remote-control it as a corporeal avatar, or perhaps even grant "her" with some level of self-awareness in a Robot Me kinda way, or split the difference at a two-member Hive Mind — one Lash in Harry's head as always and another as an Artificial Human, both helping and annoying him in equal measure.
They could even go the whole way and put the entirety of Lash's soul in a long-lived homunculus, but that sounds like a bad call given how Harry's survivability would nosedive without Lash riding shotgun in his mind. And that's before considering how bad an idea would be leaving him alone with the Winter Mantle.
Now, why would a Puny Earthling be "supporting" heavy hitters such as "six Mother Goddesses, and thirty-seven each of the strongest Angels, Devils, and Valkyries" in an operation with at least an Class X Apocalypse How as the price of failure? It would make sense if said human was a Starborn, who through "a complex confluence of events, of energies, of circumstances [was born with] the potential to wield power over Outsiders."
From the The Dresden Files novels we know of one, maybe two, characters that fill the bill. And one of them we know for sure would risk a Fate Worse than Death to keep the world safe, perhaps even to the point he jumped into the seal so the Walker couldn't use him to drag itself out of the trap.
It would explain why there isn't a DxD!Harry in Bizarro World — "Ur-Harry" didn't technically die, or at least he didn't within his home Creation, meaning that his Soul didn't rejoin the Circle of Reincarnation and DxD!Harry was never born in modern times.
As for why Harry was born before Houdini died, well, they lived in different Creations/Universes that work under very different fundamental rules. Who is to say that jumping from one to the other doesn't have Timey-Wimey Ball side-effects attached.
Maybe the whole reason why Harry de-aged to his teens upon entering Bizarro World is because the local universe partially recognized him as Houdini and "corrected" his age by taking away his last 30 years or so, which is the amount of time Ehrich Weiss has been dead according to the rumors. It wouldn't be that surprising considering such an unique set of circumstances and the fact that Bizarro World's reality is canonically stated to be glitchy since God's death.
Both Azazel and Serafall saw something about this when Harry Soulgazed them and unconsciously made the connection between him and Houdini, which is why they wrote Harry's In-Universe fictional counterparts as a descendant of the last true wizard.
Finally, if this is true, it would mean that Harry didn't ended up in Bizarro World by pure chance. His soul simply came back home at long last.
- Harry has made reference to searching for the Bizarro World counterparts for his friends and allies, as well as himself. While several of them do not exist, such as Harry himself, one of the confirmed counterparts is of one Karen Murphy, who seems to be living a much happier life without being involved with Harry Dresden. However, she may not be safe. As the light novels have shown, the Chaos Brigade is not above kidnapping the families and friends of their enemies, like how they kidnapped Issei’s family in a later volume. My prediction is that the Brigade or some other foes will find out about Harry’s search and come to the conclusion that Murphy is someone who Dresden cares about. The Brigade will then kidnap her in an attempt to use her against Harry, forcing Harry to explain just why he was searching for a police officer on in Chicago and just how he knows her, either to his friends/lovers, or to Murphy herself.
- Harry is someone the Outsiders are wary of, especially given just how far he has gone to fight against them. The Outsiders KNOW of Harry and his deeds, which makes it a fair assumption that He Who Walks Below, also known as Trihexa, might know of him as well. So, when Trihexa is released by the Chaos Brigade, I predict that 666 will recognize Harry and “out” him for who he is. Alternatively, Harry has been slowly working toward letting go of his hold-ups about his past and his fears that the truth will drive away those who has come to love and care for in Bizarro World. I predict that, in the battle against Trihexa, Harry will finally let go and out himself, revealing his origins and deeds in a speech worth of an epic hero, such as labeling himself as “Lord of Demonsreach”, “Knight of the Winter Court”, and “Starborn”. I imagine this could be a sort of callback to the first chapter of gabriel blessing’s story, where Harry gives an epic speech against He Who Walks Behind before being sent to Bizarro World.
Jossed and Confirmed
- For extra awkwardness, Jeanne's little sister is a fan of the show. This means that the above development would give her the wrong idea about Harry and Jeanne. Whether Alice gets behind the pairing or merely has This Explains So Much moment, Hilarity would Ensue.
- Jossed. The Dark Magical Girl role in the Show Within a Show went to Georg, or rather "Georgia", who's the Wandering Wizard's Old Flame (or so she tells herself), former magic apprentice, and currently a Stalker without a Crush.
