After that she'll be locked down in the Londinium palace placing orders to have some of Gallia's more exotic weapons shipped over, and working on making that air cannon work without the Heel Stone.
Sheffield mumbling : "Kill Faeries must kill Faeries must kills Faeries before they come eat me . . ." Continues hammering together ancient magical artifacts with two by fours and a wrench.
Great, I'm now imagining her as somehow double titaning. Once to get the human sized body, and then again to get up to Abyssal Queen.
Funnily I was thinking something similar crossed with Envy getting his body back in FMA. Lots of cackling glee and a giant euphoric power rush as the Abyssal Queen begins to regrow all around her and she sort of squirms back into her titan sized form while unlimbering all of her old powers in delight.
Come to think of it, living as an Apex hyper predator might also explain a bit about Octavia's personality, or differences between the two showings so far. She's a prideful little shrimp to begin with, she needed to be to endure and survive as such a small and weak creature, but wearing the Abyssal Queen or sleeved into her Not!Asuna form she's innately going to be far more secure, confident, and
aggressive and backed by enough power at her weakest to match top Faerie mages (while seemingly not needing to chant to use her magic).
Octavia might turn out friendly, but I would expect she'll remain haughty and prideful. And probably continue to tease Asuna about Kirito.
Edit: Or god forbid she sees Kirito go full Gleam Eyes.
<<Asuna waved a hand before her mermaid doppelganger, Octavia seeming not at all aware as her jaw hung slack. The battle between Kirito and the Jotun had stolen away her voice it seemed, and left her senseless. And if they stay out in the open like this it was going to do a lot more than that.
Just as Asuna thought these words, Kirito brought his great sword down in a sweep that cleaved the Giant from shoulder to hip, only bringing the monumental weapon to stop by supreme force of will as every muscle in his frost matted torso trembled.
"Octavia!" Asuna grabbed the foolish girl as ice chunks the size of bolders fell around them. "We have to get out of here, Kirito-kun is . . ."
"Kirito-kun?" Octavia asked distantly. "
That's Kirito-kun"
"Yes that's Kirito-kun!" Asuna explained quickly. "He's fighting so that we can get away . . . Octavia?!"
The mermaid was pinching her cheeks as she looked up starry eyed. "Yggdrasil-sama! He's gorgeous!">>
