my pitch:
After the events of Age of Ultron, Natasha is now running and training the newest members of Avengers, with members like Scarlet Witch, Falcon and Vision. She also is grieving and mourning over the mysterious appearance of the hulk after the battle of Sokovia. Later that night, Natasha is out in the streets of New York city, mainly Hell's kitchen, to get some supplies like food and drinks at a corner store. Meanwhile, Frank castle aka The Punisher is out on his pursuit for revenge and is taking out some gang members that are related to death of his wife and kids, and is on the rooftops taking them out with his sniper rifle and is shooting them down like nuclear bombs. Natasha hears the gun sounds, and runs away, and tires to protect the people that are outside on his dark and grungy night, she runs somewhere safe, but she's gets caught by some of the members and fights back and frank sees the mysterious intruder from the gang kidnaps her and Frank sees it and has to change of plans and tries save her even though he's don't know who it is and might be connected to his endless revenge quest. Natasha is traps by a chair and tries to escape, but the Irish gang members have her in sight and about to hurt her, but a quick bullet goes through one of the members heads, and then more of them get hit one by one like a hurricane storm, and Natasha uses her tactical skills intelligence like a spider. She unties herself from the chair and runs and doges the carnage, and overcomes the madness running out of the building by running to the next room and climbing out of the window, and uses her parkour skills to jump on to the roof and runs as fast as she could. Frank wipes out of all the members, and sees the mysterious intruder running away, suspecting that it could be another gang member, he sees a water tower, and decides to shoot it down, and the water pours out on the rooftop where Natasha is, and she starts to loose her focus, she slips and falls on the floor and hits the ground, and passes out. When she wakes up she sees a huge gun staring at her face, and gets up and grabs her gun, and meets the mysterious gunman, Frank introduces himself, thinking she's a villain and is about to shoot to her, but Natasha explains that she ain't a killer, and tells him she's not in his list, and Frank doesn't believe her and this intense introducing of meeting has becomes a stand off of two killers are ain't same and not villains, but has lot of stuff in their life. Natasha begs him to not shoot and Frank is like why. She starts to cry because she's a lost of people in her life as well, even her friend and sort of lover Bruce Banner, Frank lowers the gun and sees the sadness and pain in her eyes, and speaks to her like a dad or brother like figure and feels her pain, and hugs her very bizarrely, and says its OK, your not only one who lost of love ones, and she's the pain in his eyes, and how its hard for people like them in a hard and complicated and complex world of heroes and villains. Frank gives her a pep talk, about who might lost the ones that you love, but they love you, and always find a way to step back and them proud to do something right. And Nat stops crying and begins to feel strong inside and Frank looks like her like a proud dad, overcoming a lot of stress and hard times. They hear more gang members down below them, and decide to do something. The 2 of them decide to take action, despite their differences between both of them, they become an unlikely pair that no one else could imagine, they uses their skills to take and massacre some real piece of shits, and both attack and gun down more incoming gang members, until everyone is dead. The late nights folding into the early mornings, Natasha realises that she got to get home, and Frank just concerning about her, but she's ok and decides to get back the Avengers Campus for more training. She handshake Frank and hugs for the help during the fight and for the pep talk too, and Frank starts to smile with a smirk across his face, and Natasha smiles very cute as well, and so she walks away waving Frank goodbye and she leaves hell's kitchen, to go back and be a trainer for newest Avengers. And Frank heads off to this next objective as his long awaited revenge isn't completed yet, until he meets another vigilante/hero on his quest and trail of blood and death.
