Lightning stared out the window she remember her favorite flashback when she was still Claire.
Flashback...
Little Claire and Little Serah was running to see the beautiful fireworks. Serah was five and Claire was seven, Serah peeked through the crowd and said: "Claire I can't see!" Claire smiled and lifted Serah up to her shoulders as she watched the fireworks her eyes widened she said: "oooh...it is soo beautiful." Claire smiled and said: "You are silly little sister." Serah smiled and said: "I'm not silly! I'm cute!" Claire smirked and pat her head said: "I love you." Serah jumped up and down and said: "I love you too Claire!" Serah quickly hug her sister and went back to her house."
Lightning felt that a part of her is lost when Serah became Cocoon's enemy, when she saw Serah lying on the cold floor she quickly went to pick her up. Serah gently touch her face and said: "Claire?" Lightning said: "Yes Serah?" Serah's eyes was filled with tears said: "I'm sorry I've been a burden to you." Lightning shake her head and said: "You never been a burden to me! You were always my precious little sister that I loved and cared." Lightning started to cry, Serah stare at her elder sister she never saw her cried when she changed into Lightning. Lightning started to remember what happen when she got hurt on her first mission.
FLashback...
Lightning held her wound as blood dripped out, she finally made it to the door magically the door opened. Serah quickly opened the door and pulled her in, Serah looked at her and said: "Do you know how worried I was!" Lightning nodded as Serah led her to her room, she quickly bandaged the wounds as Lightning said: "Serah.." Serah looked at her and said: "Don't talk." Lightning still manage to talk said: "Did you skip school?" Suddenly Serah pressed the cloth harder and Lightning yelped, Lightning grit her teeth said: "Serah that was mean..." Serah smiled and said: "I learned it from you." Lightning smiled her baby sister grown up.
Lightning then felt Serah's hands turn normal now she was no longer a crystal, Lightning smiled and hugged her. Lightning hugged her tightly and said: "I'm so sorry I didn't listen to you. I almost lost you." Serah felt that Lightning's wall and defense starting to crumble as Serah softly kissed Lightning on her forehead said: "Claire don't apologize, apologizing is for strangers but you are not any stranger you are my best elder sister I could never have anyone as best as you." Lightning's uniform started to disappear as she return back to the clothes she wore when she was Claire. Serah looked at Lightning and hugged her tightly: "Its you Claire! I miss you!" Claire and Serah hugged as they arrive back home.
