Had hisoleo been canon during the Hisoka Vs Chrollo match(Spoilers)
Imagine Hisoka telling Leorio, strictly, not to go see his match.
What I think would happen if Leorio went to go see Hisoka's match(and if the hunters association was in the republic or Padokea, making it easier for Leorio to just stop by):
Leorio would go to heavens arena anyway just to make sure Hisoka is doing good. Making sure bae is fine Hisoka told him strictly, even sort of threatened him, to stay away from the match. The magician fearing Leorio's well being when in reality he should be fearing his own safety. What's so different about this match compared to the others? Who is Hisoka fighting exactly? Hisoka haven left out that it was a death match and with Chrollo Lucilfer.
Leorio couldn't resist going to see the match. He's literally eyeing the whole show from the entrance in a ridiculous disguise or something, all the while using zetsu so Hisoka wouldn't immediately notice him. But knowing Hisoka, he would probably sense Leorio there anyway. So Leorio decides he'll only be here for the beginning of the match- HISOKA'S FIGHTING CHROLLO!? THE SPIDER? Didn't Kurapika seal his nen!?
As Leorio watches the two exchange words, he's tense, frozen in place, and clenching his jaw hella hard in anger. Here goes Hisoka again doing whatever the hell he wants without thinking of others, not even his own boyfriend. Leorio moves closer towards the seated people, wanting a better view of the match. Death Match they've agreed to, and Leorio felt the inevitable feeling of his stomach sinking. Will Hisoka succeed?
A minute into the match and things don't looks so great, Hisoka looks like he's having a hard time. This is bad. Leorio can't just sit here and watch this play out. Should he call Kurapika or something- No.? That might only make things worse. Kurapika would not only blackout with rage, but Hisoka might attack him for disrupting their fight. Chrollo would be killing two birds with one stone.
Explanation this, explanation that, Chrollo making a double of the dead referee. Leorio shudders at the intense aura washing over the whole arena, intent to kill. It's a chilling feeling, like being trapped in a cage with three tigers. Leorio's having a hard time keeping up with what the hell Chrollo is saying, what with the crowd shouting and placing their bets on who will come out victorious. So Chrollo can use someone's aura even through their passing, or did he hear that wrong? And the bookmark is to keep track on his ability or- THERE'S TOO MUCH TALKING.
"What are they doing?!"
Shit. Chrollo is jumping towards the audience and Hisoka is following suit. Leorio hesitantly stands his ground, watching from a distance. He's about to make an exit to the door's entrance, but is frozen in place watching as Chrollo is using people from the audience to attack Hisoka.
Everyone is now scurrying away, trying to push through to keep at a safe distance from the two. The shoving crowd blocked Leorio's view, and like Hisoka, he can't make out where Chrollo is. He's hiding in the crowd?
"WHAT-WHATS THIS?! THE AUDIENCE IS RUSHING AT HISOKA?!" –Coco the Commentator shouts.
"What are they doing!?" Leorio watched wide eyed as people from the audience went after Hisoka. "Damn it!" Leorio wants to help. He needs to help. He can't just stand by and watch as dozens of people pounce on Hisoka. But he knows he'll only get in the way. Maybe if he uses his warp punch? But where is Chrollo-
Hisoka is struck from behind by said spider. Leorio near runs to his aid… if it wasn't for that creepy smile Hisoka has on?! Is he really enjoying this…? He's losing!
Although Hisoka is having a hard time beating the crowd, and with Chrollo popping out here and there, he's still smiling? Fucking Masochist. Those punches and kicks look like they can shatter a bone too. Leorio flinches each time Chrollo lands a hit. And right when all hope is lost for the damn clown, right when Chrollo stomps on Hisoka's face, Hisoka manages to strike Chrollo across the face.
"YEAH, GET HIM, GET RECKED SPIDER!" Leorio shouts, cheering whist Hisoka managed to strike Chrollo again on his left side. Hisoka has the upper hand now, already defeating the crowded people around him.
Chrollo disappears right into the audience, and Leorio chose to use the opportunity to make his leave. He doesn't want to be caught up in the two's bloody game. Hisoka looks like he's got things under control. Leorio can leave without a worry, right?
Leorio is quick to move out of the way, shoving past a number of cowering yet intrigued people, but oh wait- there's a woman and child in distress. SHIT. WHO WOULD BE STUPID ENOUGH TO BRING A KID HERE? Leorio makes a move towards the two, wanting to help them-help the child mostly.
He grabs the woman holding the screaming child and yanks her along with him, towards the exit. "This is no place for kids!" He scolds, using Ko to have an easier time pushing people out of his way.
"It's Chrollo"
"Run!"
"MOVE!"
Leorio stops, backing up and shielding the woman and her child.
Chrollo, soon after making a copy of some random victim, approaches Leorio, eyeing the taller curiously.
Leorio swallows thickly, tearing his gaze away for a moment to search for Hisoka. Said man is following after another Chrollo!? Chrollo can double himself?!
"You're friends with the chain user," Chrollo speaks, thinking back on his first meeting with Leorio. "Are you enjoying yourself?" He asks humbly, as he took a few steps forward. "Is the Chain user here as well?"
"Go hide." Leorio tells the woman.
"It seems he isn't with you, shame," Chrollo summons Shalnark's Black Voice in hand, needle appearing in his other hand. "Are you here on your own accord?" Chrollo asks, sounding normal and not like he's about to do something to Leorio. "Or did you come for Hisoka's sake?"
The twitch in Leorio's eyebrows was enough answer for Chrollo. "So Hisoka," Chrollo starts, dashing forward and appearing behind a startled Leorio. "Do you think he'd hold back fighting you?"
Leorio's eyes widen and his heart stops once the needle stabs his neck.
"Stay home, under no means do I want to see you at the match, Leorio. This one is… unique… ha ha, don't worry much about it, love, I'll come visit you as soon as I win~"
Imagine how conflicted/ how out of control Hisoka would be had Leorio been used as one of Chrollo's puppets. :^)
