When they walk out from the Brew, Hanna notice something in Alison's bag. It's...a gun.
"Ali, what are you doing with that?" says Hanna.
"Doesn't this top look good on me?" says Alison confused.
"I wasn't talking about your neon-green top. I meant that gun in your bag." says Hanna.
"Han, I'm sorry." says Alison. "I really am."
Alison pull out the gun, hold it with both hands and aim it at Hanna.
"Ali...what are you...? Did you kill that red-head girl...? You thought it was Em's friend, didn't you?" says Hanna.
"Yes and yes, Hanna-Boo. Now you have to face the same faith as that girl." says Alison. "Bye, Hanna Marin!"
"No way!" says Hanna as she swing her bag and knock the gun from Alison's hand.
Hanna quickly grab the gun, jump into her car and drive away.
"You've not seen the last of me." mumbles Alison.
Later in Emily's bedroom.
"Ali did it. She killed Anastazia's sister." says Hanna.
"Oh no..." says Emily.
"I don't like it either and Ali wanted to kill me too, she almost did." says Hanna.
"We need to tell Aria and Spencer about this." says Emily.
"I will, as soon as they get here. I called them." says Hanna.
"I knew Ali isn't always a good girl, but I never thought she would kill someone." says Emily.
"Neither did I, Em." says Hanna. "She's always been bitchy and kinda rude and still I used to think that she was nice somewhere behind all that."
"Han, Em, why did you call for us?" says Aria in a mature tone as she and Spencer enter the room.
"Ali is a killer. She's the one who killed Anastazia's sister and today she almost killed Hanna." says Emily.
"Hmm, apparently some people doesn't have limits." says Spencer.
"I can't believe that Ali would try to kill people just for the remote chance to win Emily's love." says Aria.
"Alison's gone too far. We need to stop her before she hurt someone else." says Spencer.
"Sure, but how?" says Hanna.
"Leave that to me." says Spencer.
"Uh...what exactly are you gonna do, Spence...?" says Emily.
"I don't know yet." says Spencer.
The next week.
Aria, Hanna and Emily are hanging out in Hanna's room.
"My plan is ready." says Spencer as she enter the room.
In her hands, Spencer holds a gun.
"You're going to kill Alison?" says Hanna.
"Is that really such a good idea, Spence? Like an eye for an eye?" says Aria.
"Murder's wrong...no matter who's doing it." says Emily.
"Oh, I thought you'd praise my ideas, as you usually do." says Spencer.
"Well, usually your ideas make sense..." says Emily.
"Spence, if you kill Ali, you're no better than she is." says Aria. "It wouldn't be justice. It would be vengeance."
"I'm open to suggestions..." says Spencer.
"I have no idea." says Hanna.
At the same time, Alison throws her gun into the lake.
"Fuck!" says Alison.
Later the same day.
"Hanna Marin will die." says Alison as she sit down on her bed.
Alison remember the time she first met Hanna. It was back when Hanna was still chubby and insecure.
Way before Hanna lost weight and became confident and sexy.
"Shit, why did I ever let Hanna join my gang? Hanna's bad news for me." says Alison.
Alison is not happy.
The next day when Hanna walk along the hallways of Hollis on the way to class, suddenly Alison walk up behind her and try to stab her with a big knife.
"Stop there, Alison!" screams Emily as she use a powerful karate punch to knock down Alison.
"Awww! Thanks, Em!" says Hanna as she gives Emily a kiss and hug.
"Awww, Hanna-Boo!" says Emily with a cute smile.
Later that day, two police officers takes Alison to Radley where she'll stay for a few years and be treated for mental disorder before she can get her freedom back.
Almost a years later, Emily and Hanna get married. Emily finally has her cute Hanna-Boo. They know that they have powerful true love that can never be destroyed.
The End.
