Read The Bridge
 
“In the car ride, I could tell the alpha siren’s questioning caused you some distress. Why haven’t you told her about your…”  
He took a glance at her hair streaks. While the neon green had returned, her features remained slightly different on other parts of her body. Her skin was a slightly darker hue of purple, as was the majority of her hair; and while he wasn’t quite sure, she seemed to have grown a few centimeters taller than when he first met her.  
“-condition?”
 
Aria Blaze was still for a moment, raising up a palm looking at her hand in a manner that made X curious if she too had notice the slight color change. Regardless, she still said nothing.
 
“You must know she suspects something.”
 
Aria’s hand balled into a tightly bound fist.  
“…. Sometimes I trust my dear cousin only a bit more than I do you.”
 
“Thought I sensed some internal hostility.”
 
Aria Blaze shivered and jittered for a few moments. Her lips quivered briefly before turning into a snickering smile. Before long she momentarily broke into a spurt of laughter that was more than a little eyebrow raising for the kaiju.  
“Hah..aha.. AHAHAHAHA! Aaaaaah! Hostile?~ Oh why would I eeever want to be hostile towards the Great Adagio Dazzle?! Out great leader who always strove to be the best of us with noooo competition? The prettiest, the most confident, the apex and the main singer of our little choir. The bold siren who spurred our glorious rampage across Equestria that got us stuck here! Cut off from home! In the bodies of some naked monkeys!”
 
Aria lashed out, but in the opposite direction to where X was standing. She threw backhand to the sapling beside her perch, hitting hard enough to snap a limb and crack the trunk despite opening up a cut on her hand. She hissed out her breath, letting her head droop down and fall limp. She still spoke with venom on her tongue, but a manner that seemed more saddened than enraged.  
“I tried to caution her… I should have tried harder, but she. Never. Listens….If she knew about this power, how much stronger I am with it, she’d just mess it all up by wanting it for herself to avoid a threat. I’m done singing second chord.”
 
“So, you want to exceed her, despite also wanting to use that same power to protect her and the other siren?”
 
Aria shrugged, pulling her striking arm out of the trunk and looking down at her amulet as she held it out.  
“With our little choir, family never is a simple matter.”
 
Not wanting to risk causing another tantrum and wasting the night, X diverted the subject away from Adagio. There was something about what Aria had said he’d taken notice of.  
“You said before you came from a form different than the humanoid and lost your home with the change, but didn’t specify. What was it? Where did something like you come from?”
 
Aria sighed, sitting back up. Memory traced itself back to another world, both figuratively and literally. For a split second, she had to resist a tiny smile from the nostalgia.  
“The sea. We sirens can travel overland by floating if we wanted to, but we’re supposed to live in the ocean.”
 
“Haven’t seen an ocean in a long time. We didn’t have those where I was stationed most of the time. Hard to imagine all that water in one place sometimes.”
 
Monster X muttered whilst staring off into space at the thought. Aria pulled her legs up and rested her chin upon a knee, shrugging as the tiny smile flat-lined. Being cut off wasn’t something she fancied reminding herself about.  
“Yeah, it’s where I grew up. We’d travel overland sometimes, but always went back to where we came from soon after.”
 
Monster X tilted his head in her direction, looking the saddened siren over out of the corner of his eye.  
“You missing it is what’s fueling your anger for the alph…. for Adagio, isn’t it?”
 
“You wouldn’t be wrong… Tidal ebb and flows, kelp forests, moon beams at night and sun rays by day near the surface, with all the calm blackness in the depths; all the sailors or coastal folk we could ever hope to prey upon…. Yeah, you wouldn’t be wrong in guessing at that reasoning.”  
She murmured with a snort. After a few moments in silence she picked her head back up and looked over at the soul she’d been conversing with, unconsciously shivering and growing a frown when she spotted his red eyes looking right at her.  
“… And what’s the deal with you? One week you’re running me through the wringer and asking me to hand over my lifeblood on a platter, next week you’re asking for my life story. What sort of place did a monstrosity like you come from? Did Starswirl go dredging through Tartarus to find a bounty hunter?”
 
She grunted with a raised eyebrow. X fortunately didn’t get invested enough to take any offense, instead wordlessly looking up at the magnificent carpet of stars high above. It was a fortunate side effect of him picking a spot far away from any habitation for the session, meant less light pollution to filter out the cosmos. He waited a moment, moving his focus of vision about as if trying to locate something in the black sea of light and blackness beyond.  
“I do not know who this Starswirl is; I’m not of this realm or the one you came from. But, based off the constellations above-”  
He muttered, raising a hand and pointing at a particularly bright star near the middle of the horizon just above the treeline.  
“-that blue one is actually two stars close together, you just can’t tell from here. My earliest memory comes from orbiting the fourth planet in that system.”
 
Aria squinted, spying the star, or rather stars, in question for a good five seconds before the realization dawned on her. She spoke in a disgruntled tone, half convinced she was being lied to or misdirected again. If there ever was a concept she found ridiculous since learning human culture, it was the sixty year old science-fiction movies Sonata kept watching.  
“…. Seriously, you’re a space alien? That’s ridiculous.”
 
“Said the mind controlling sea witch in human form .”
 
“….”
 
“….”
 
“…. Touché.”
