Assassination target#2: Fiona Fox.
Leonardo walks into the streets of Station Square, only to see a slightly wounded Cream with a knocked out Amy. Cream said "Leonardo, you're here. Listen, Fiona has taken Tails and she's going to carry him to her house."
"Molto bene Cream. (Very good) I best save him." Leonardo tracks Fiona carrying Tails and walking to her house, which was 19 yards far from her. The red fox was getting suspicious so she looked around, but she saw nothing. Leonardo rolls to a dumpster to hide from the red fox. She still turned her back but saw nothing. Then however she walked all the way to the streets jaywalking without getting a scratch, thinking "Never gets old." then laughs evilly.
Leonardo, on the other hand follows Fiona by crawling down to a dumpster that leads to the sewer. He lands to a pile of boxes then walks through the sewers with Eagle Vision. Until then, he runs through the sewers by jumping through gaps, opening closed canals and entering old doors that lead to the other sewer levels.
Fiona, on the other hand, kept walking while carrying Tails, causing unnoticed trouble along the way as she walked home (without using a car, since she doesn't have one) such as kicking a garbage can, steal 3 wallets from people, stealing coins from a beggar and even take a bagel from a cafe table. She smirked evilly and said "This shit never gets old."
Then Leonardo, who was following Fiona, ran all the way through the sewers while following Fiona. He thought "This better end up too well. So, what the hell am I gonna go next in this filthy sewers." then passed through. The red hedgehog was always struck at the fact that he had to kill to save his friends. He was unsatisfied at this idea. After reaching her house, he ended up lock-picking the front door, then opens the door.
Fiona's house was different from Scourge's apartment, it was a pile of garbage, there was lots of trash thrown to the floor; the coffee table was filled with tar and oil, the TV was covered in a towel, and the trash can was overfilled with lots of food wrappers. Leonardo walked carefully to the bathroom, but the door's lock was broken and he couldn't get in.
Leonardo stepped in the kitchen only to see the fridge broken, but still used. The sink full of dirty plates, the cupboards were torn down, and the stove and oven were broken down as smoke comes out of the oven.
Leonardo tries going in the bathroom, but the door was locked and that he did not bring any lockpicking tools to go in. Despite that, Leonardo steps out of Fiona's house, disgusted while commenting "Lurido puttana! (Dirty whore!) She never bothered to cleaned up any of her rifiuti (trash)."
Fiona was still tired as she stepped in the construction yard, tired as she placed Tails in a chair, later on she heard "Ehi, lurido puttana! (Hey, dirty whore!)" she responded when the red hedgehog walked to her "You must be Leonardo." though it was not complicated as Leonardo punches her in the muzzle, she reacts angrily "What the hell?!"
Leonardo responded "You wander around the city, making trouble without the police noticing." Fiona responded harshly after spitting on Leonardo's face "It's you that everybody calls whenever Sonic and his buddies aren't around, are you afraid to handle things yourself?"
"Your Scourge must have survive for what I did to him." Leonardo retorted after wiping the saliva from his face. Due to this, Fiona becomes angry that Leonardo killed Scourge and yelled "You killed him. I'll fucking kill you!" then pushes Leonardo to the ground as she jumps to stomp on his face. But Leonardo rolls out of the way and gets on a fighting stance. Then Fiona charges at full rage.
A intense fight occurs in the construction yard, at least when they fight with high effort. But Leonardo was too defensive that he kept blocking Fiona's kicks and punches until he punches Fiona in the stomach and throws her to the ground, getting a heavy scratch. Then she stands up and attacks him but Leonardo keeps blocking more of Fiona's kicks and punches, until he counters by twisting her leg, causing her to scream in pain, then kicks her to the wall.
Fiona was still able to stand up, but before she can charge, Leonardo runs at her at high speed, then jumps so high then lands on Fiona, and stabs her in the neck with the Hidden Blade.
At her last words she said "I swear I won't forgive you. You killed Eggman, Scourge and me. Who else will you kill?"
"Anybody who can pose a threat. Va' ora, che sia il tuo pieta ne alla mente. (Go now, that your mercy is at last be still). Requiescat in pace. (Rest in peace.) " Leonardo responded which caused Fiona to die peacefully as Leonardo closed her eyes.
After 5 minutes, Leonardo walks out of the construction site with Tails, whom he woke up and untied later. Tails asked "You had to kill Fiona in vain. Why?"
Leonardo answered "No villain should be allowed to live, whether they are Templars or not."
Tails said, marveled "That was awesome of you to save me. I mean, no one has ever saved me since it's always Sonic who saved me. I'll repay this. I swear when you come to my house. Someday, I will." then runs home. Leonardo walks to his home, again moving to his basement access to the guest room, pulls out his checklist with pencils and crosses Fiona's name. After that. Leonardo closes his basement access and sits down on his kitchen table, drinking a bottle of Mountain Dew, thinking...
"3 down, and 2 to go. That's all I can say."
To be continued...
3 meant that Eggman, Scourge and Fiona has died. 2 more means is unknown. Sorry. Just two more and the story's finished.
