Erza was starting to think this through.
What if their lives were connected at some point. The twins could've been her childhood friends from before Tower of Heaven .but that still didn't explain why they look so much like her. She thought for a little while but couldn't figure anything out.
What could be between them? What would connect them in this way? Why did they look like her? Why were all of them able to reequip? So many questions and so few answers.
Erza opened her eyes wide when she got a flashback.
Flashback
The door opened into the room where four years old Erza was sleeping. She had been awake for a long time and heard the panic rise in the village. Erza's mother ran into the room and to Erza's bed. She was pushing two little girls in front of her. The same girls as in Erza's flashbacks.
"Erza take care of Aki and Aya as good as you can. get away from here. Be safe" she told Erza looking into her eyes.
Erza nodded her head. "I will mom" she said silently.
"But mommy what about you and dad?" one of the little girls asked.
"We'll make sure no one follows you," the girls' mother whispered.
"Be careful" the other cried wrapping her arms around her mother's leg.
"We will Aya shh don't worry about us" their mother whispered calming the younger of the girls.
Yelling was heard from just outside the door.
"Hurry they are coming!" A male voice yelled. Erza's dad.
"Be careful" their mother whispered before she ran out and locked the door behind her. Erza knew they were supposed to escape through the window but she could hear the men out there as well.
Erza opened the closet. "In here you two" she commanded.
"But what about you big sis?" the youngest asked.
"I'll be fine" Erza said looking to the other girl. "Aki take care of Aya from now on" she ordered and pushed the girls in the closet before locking the door shut.
She stayed for a short listening to the men. They had passed the window. She could get out herself. There was no chance the twins would be found and she could handle this herself. They would be safe
End of flashback
Erza gasped. Now she knew who these little girls from her flashbacks were and why it was all connected.
"You two…" she whispered. "You two are my younger sisters" she felt the tears in her left eye.
"Your… what?" Aki asked.
"My younger sisters" Erza smiled pulling them into a tight hug. "I thought for sure you were dead a long time ago!" she cried.
Aya cried too. "I didn't even know! I'm sorry" she cried.
"Don't cry Aya" said Aki who was crying hard herself. "You're making me cry too"
Aya just cried even louder by hearing those words. "Big sis" she cried hugging Erza tighter. All of them group hugged for a little while longer before finishing dinner, eating it and going to bed all tree of them fell asleep with smiles on their lips.
