It has been a long few months since Louise had left vault 111 and became the leader of the Minutemen she had travel the wasteland helping all those that needed it. She had united the settlements took out the gunners and raiders of Nuka-World. Now she is standing in the Institute with her son Shawn "so this is how it all ends?" he asked letting out a cough.
"I'm sorry Shawn I didn't want this" Louise said as tears fall from her eyes.
"I am sorry as well mom" he said coughing some more he looks over at his mother.
"We both wanted the same thing a better world" Shawn said.
"I want you to go over to my computer and upload the information to you pipboy" he said as Louise nodded as she walks over to the computer.
Once she was on it she uploaded everything the Institute had onto her pipboy and send it to Codsworth "there it's done" Louise said walking back over to her son and taking a seat next to him.
"Aren't you going to leave?" Shawn as as he starts to cry he didn't wanted his mother to die as well.
"No I send everything to Codsworth he will give it to the Minutemen and they will use the knowledge to make the world a better world" Louise said.
"I thought this might happen" Shawn said as he coughs a bit as he press a hidden button.
"There I sent out the very last synth the Institute will ever made a synth of you" Shawn said with a smile.
"Replacing me with a synth are you sure that's a good idea?" Louise asked her son.
"Don't worry I may not be the one to have it made but I did a few reprogramming she knows she is a synth she has all your memories" he said.
"When were you able to get all my memories?" Louise ask confused.
"When you first enter the Institute when you teleported in it was able to scan you as you entered" he said with a smile.
"I always thought you would grow up to be smart" Louise said with a said smile.
Mother and son shared one last hug while there was a loud explosion and a large flash of light. Outside on top a large tower overlooking where the Institute is the Minutemen watch as the explosion burst from the ground as fire shot up to the air as the ground shakes "it's over" said Piper as she watch as the explosion dies down.
There was a flash of blue light they turn to see Louise wearing a institute uniform "it's good to see you're back but what's with the getup?" ask Preston.
"Sadly I am not Louise I am a synth created to replace her but the leader reprogrammed me" she said.
"Why are you here?" asked Piper as she was ready to pull out her weapon.
"I was sent here to help the wasteland and make it a better place" she said.
"You can see where we might find that hard to believe" said Nick.
"I can understand that but I have nothing to gain by lying to you all" Synth Louise said.
"We should give her a chance" Codsworth said.
"Are you sure that's a good idea?" asked Preston.
"No, but I am just a robot program to serve and she may not be the real miss Halford but she is a Halford and I will serve her and like she said she has nothing to gain but we all do if we let her" Codsworth said.
After hearing this the others started to talk among themselves they then walk over to Synth Louise "we agree to letting you join us but you will be watch" said Preston while the other nodded.
"Thank you for letting me join" she said with a smile.
"Yeah just don't let us regret it " Piper said.
After Synth Louise join the others it turns out to be the best thing they ever did the Commonwealth started to get better soon more Riders were found and removed from the area keeping the place safe. They use the tech they got from the Institute to help clean up the radiation so the food can grow better. It has almost been a year since the death of the real Louise Halford her synth standing on the same tower where everyone watch the destruction of the Institute everyone notice how she is much different than the real Louise. Walking up behind the synth was Preston "you have done a lot for this place" he said to her.
"Yeah I just hope the real Louise would have been happy with what I have done" she said looking out to the horizon.
"I am sure she will you have her memories so you would know how she would think" Preston said.
"That's true but I feel a lot different than her as well" she said.
"Ever thought it's time for a change of name?" he ask.
The synth looks deep in thought then a smile appears on her face "Alice, Alice Liddell" The newly name Alice said.
"Nice name, why did you pick that one?" Preston ask.
With a smile she turns to look at the setting sun "because watch me turn this wasteland into a wonderland" she said.
