[spoiler]Just a little bit of ambiguously canon drabble that I felt might explain a little about Lillianna and the future she comes from, even if it didn't quite turn out the way I'd hoped.

A house somewhere in Black City, nearly two decades after the J-Team's adventures

-In her bedroom, a teenage girl is sat on her bed with her knees pulled up to her chest. Her body is beginning to show signs of malnutrition, and her unkempt brown hair is tangled into clumps. She stares at the glowing television screen in front of her without truly watching it, her eyes almost glazed over.-

Newscaster: ...the owners of a prominent martial arts dojo were found dead in their home in Unova earlier today following signs of a violent struggle. Local authorities believe this case to be linked to the recent string of so-called "Avenger" murders across the region, but have no leads on the killer's-

-The sound of someone making their way up the stairs snaps Lillianna out of her reverie, and she hastily scrambles to her feet, switching off the TV. Sure enough, the door is opened a few seconds later by an adult Lucius, far taller and broader in the shoulders than his teenage self ever was. His usual drab attire doesn't appear to have changed one bit, with the exception of the crimson stains marring the front of his sweater. He glares at Lillianna with bloodshot grey eyes that have long since lost any traces of warmth.-

Lucius: ...What are you doing?

Lillianna: Nothing.

Lucius: Oh, yeah, right. "Nothing". You don't know how easy you have it, you know. Back when I was your age, when I was going through hell at the hands of people that were supposed to be my friends, I would've killed to be doing "nothing". And yet you still feel the need to lie to your own father, even after everything I've done for you.

-He suddenly seizes her by the scruff of her shirt.-

Lucius: I'm doing this all for you, just so you're aware. I'm turning this shitty little hellhole of a world into a place that's safe for you to grow up in. I'm getting rid of everyone who got away with evil deeds once before and think they could threaten you because of it. Every single sacrifice I make is so that you don't spend the rest of your life thinking of justice as some kind of sick joke. So the least you could do is be grateful for it, you petulant little brat!

-Lillianna's eyes are drawn to the dark red stain on her father's shirt before dropping to the ground.-

Lillianna: ...Yes, Father. I'm sorry, Father.

Lucius: Hmph. Good.

-He releases her, and the two spend the next minute or so sitting together in uncomfortable silence. Eventually, Lillianna works up the courage to speak.-

Lillianna: ...Aren't you forgetting something, Father?

Lucius: Huh? What are you going on about?

Lillianna: You... you are aware what day it is, don't you?

Lucius: Of course I am. It's Monday. Why are you asking me such a stupid question?

Lillianna: ...Never mind.

-She bows her head, her hands balling up into fists, before standing up suddenly and wheeling around to face Lucius.-

Lillianna: I want to see Mother again.

Lucius: ...You what?

Lillianna: You heard me. I want to go and stay with Mother again.

-Lucius stares at her incredulously for several moments before sharply backhanding her across the face.-

Lucius: Don't you dare mention that whore again in this house, you hear me? I feed you, I clothe you, I care for you, and what do I get in return? Nothing! Absolutely damn nothing except for an endless barrage of shit like this! Is what I do for you not enough? What do I have to do to make you happy? I... I just don't want to lose you like I did her, Lillianna. I can change the world without destroying it... prove that my father was mistaken. You understand, right?

-Lillianna is silent, her cheek glowing with pain. Eventually, Lucius turns and staggers back out of the door, mumbling under his breath.-

Lucius: She left me, just like all the others... but she'll pay... they're all going to pay for what they did to me, every last one...

-As he goes, Lillianna sighs and curls up into a ball on the bed, giving a sigh before murmuring quietly to herself under her breath.-

Lillianna: Happy birthday to me, happy birthday to me... happy birthday dear Lilli... happy birthday to me...

-The sound of the door opening again startles her, and she hastily closes her eyes, feigning sleep. Instead of the sound of Lucius making a furious reentrance, however, a set of quiet footsteps approaches her bed and remains there for a moment before turning and leaving the same way they came. Slowly, Lillanna opens one eye, then the other, and notices a modest brown parcel sat next to her pillow with a note attached.-

-Lillianna stares at the note for a moment longer, before slowly and quietly opening the parcel and taking a look at the contents. Inside is a small pendant with a gold chain and a round gem clearly recognisable as a Key Stone embedded in the centre. A small, almost conspiratorial smile finds its way onto Lillianna's usually impassive expression.-

Lillianna: ...Thank you, Bishop.
