Imagine being Karen McCann's second daughter and you fall in love with Robert. (The reader is now 18 years old) 

Warning: Some mentioning of the word(s): Shoot, gun, killed,  dirty talk & cursing

Recap:   "You dirty pigs! I'll get you for this!" He yelled as you cried in the shower. "Are you, Y/n McCann?" An officer asked as you nodded. "Boss, we got her. She's unharmed." He replied to Det. Sergeant Denillo. "Y/n, are you ready to go home?" He asked as you nodded. "Can we get some clothes in here please?" He asked as he gave you his jacket to cover you. "H-He's going to hurt Megan." You said as cried. "No he's not. I'm going to make sure that Robert Doob gets put away forever." He said as he hugged you. "I want to see my mom and Megan." You said. "Okay. I'll give you some space, so you can get ready and I'll take you home." He said. After you were changed, you saw the cops hold the necklace that Robert had given you. A part of you wanted the necklace back, but another part didn't. You decided to let it go, for you had a better gift that was waiting for you at home. (end of recap) 

Once you were home, your mother and stepfather hugged you as you hugged them back.  "Oh y/n. You're home." Your mother said. "Where's Megan, mom?"  "She's with grandma. She's safe." Your mother said.  "Mom. Mack. I'm so sorry for everything." You said.  "Don't worry about it, y/n." Mack said.  Your parents went out to go pick up Megan, while you were in the shower, but although you were home, all you could think about is Robert.   After your shower, you went to your bedroom and got an uneasy feeling.  Just then your cellphone vibrated and you answered it.  "H-hello?"  "Hi beautiful.  Guess where I am? Oh and it's not jail." Robert said as you got speechless.  "Aww, what's the matter? Cat got your tongue?" He said with a chuckle.   "W-where are you, Robert?"  "Look out the window." He said as you looked and saw him waving.  "Peek-a-boo. I see you." He said as you almost screamed.   "Now kitten.  I need to know something, because little Megan's life is at state."   "W-what do you want to know?"  "Did you call the police and have them arrest me? Remember Megan's life is on the line." Robert said, darkly.  "Then tell me, Robert.  Where is my little sister?" You asked, not feeling frightened anymore.  "Oh princess.  You shouldn't talk to me like that, for that's how Julia got herself killed." He said as he snuck into your house.  

You had a plan and acted very fast by hiding in a closet as Robert came into your bedroom.  "You know, princess.  I was starting to think that you were the one who called the pigs on me." He said as you remained hidden in your closet.  "Aw, doesn't my kitten want to talk to me anymore?" he said as he circled your closet.  "I know your hiding in there, kitten. Come out and I promise to be good." He lied.   Getting fed up with this, Robert busted your closet door down and found nothing but your stuffed animals and some of your baby dolls that you kept for Megan.  "Where are you, you little bitch?!" He yelled.  "I'm right here, Doob!" You said as you aimed a gun at him.   "What are you going to do? Kill me? That's murder, kitten." He said.  "You murdered Julia and you threaten Megan. I'm not going to let scum like you live." "Scum am I? Who was the one who saved you when you were dangling from my apartment? Because as I do recall, I was the one who saved you." He said.   "I may have loved you, but now I see the true monster in you, Doob. You're a monster and a killer.  I'm never going to get my sister, Julia back, but I'm going to protect Megan with everything I have!" You said as you hit him with the gun.  "Oh, you naughty girl. Now I'm going punish you and make you regret hitting me." He said as he jumped on you and tried to take away the gun, so you would be defenseless.  "Any last words, princess?" Robert said as he pinned you down.  "Just two.  Goodbye Robert." You said as you shot him.   Robert fell backwards and died on impact.  You called 9-1-1 and told them what happened and cops came to your house once more. 

"What's going on here?" Mack said as your mother's heart dropped, thinking that you were now dead.  "Megan. I want  you to stay with daddy and don't come out of the car until I say so." She said as she ran inside the house and saw you with Det. Sergeant Denillo . "Mrs. McCann, it's nice to see you again." He said as you hugged your mom. "I got him mom." You said as all of you saw the stretcher go outside that held a body bag.  "Oh y/n." Your mother said as both of you hugged.  "You have a brave daughter there, Mrs. McCann. But I do have to ask y/n some questions about tonight." He said.  "Thank you.  Y/n? Will you be okay to talk with  Det. Sergeant Denillo?" "Yes mom. I'll be fine." You said as she went to go get Mack and Megan, who just couldn't wait to see you.   After all the questioning was done, Det. Sergeant Denillo knew that you were defending yourself and your home, but most importantly your family.  "Am I going to jail for murder?" You asked.  "No, Ms. McCann.  I see this as a break in and you did the right thing, by protecting what's precious to you." He said as Megan came running in. "Y/n!!!" "Megs!!!" You said as you hugged your little sister close to you.  "Where's Mr. Friend?" She asked.  "Mr. Friend went away and won't be coming back." You said.   Just as Det. Sergeant Denillo was about to leave, you gave him the necklace that Robert had given you for evidence.   "I don't ever want to see that necklace again." You told him as he nodded and told his crew to pack it up. Now that nightmare that was named Robert Doob was finally over.
