It was another evening. Another boring evening. The Mouri family and Bourbon decided to go fishing, accompanied by Hidemi in case anything bad happened. Rei, Ai and the other kids were at school, together with Sumiko. Kaito was off doing his 'work' somewhere. This left Sera, Subaru and Conan alone.
"I need to talk to you, nii-sama." Sera told Subaru bluntly
"Are you sure it's a good idea? Bourbon is still looking into my death. You visit the agency, which is basically his territory, every day. If he finds out you're my sister and Rei is our mother, he's bound to hurt them. He also might find out that Sherry isn't actually that, and if those things happen, then I would have totally lost..."
He paused as he started reminiscing.
-flashback-
"Another job well done, Rye." Gin praised
Rye didn't pay him any attention as he stared at the young black-haired beauty standing near the wall.
"With this you have proven that you're the one of us." Gin continued, shaking his hand.
Again, Rye paid him no attention as he walked towards the door. Upon reaching it, he stared at black-haired woman and smiled.
"I want you come with me." he whispered "I'll bring the rest of them down and take you, Akemi Miyano, along with your sister, with me."
The girl smiled. There was something else in that smile. It was despair. Rye looked past her, staring into Gin's lustful eyes. It was then that he decided to capture Gin first, to protect Akemi from him. However, he failed to catch Gin and a month later, Gin shot Akemi and soon afterwards sentenced Shiho to death.
-end flashback-
He sighed. Nowadays, Shiho, alias Ai, was all he had to remind him of his first and only love, her deceased sister. It was for this reason that he harbored deep hatred for Gin, as well as the reason he stalked Ai. He couldn't save the older sister, but he will save the younger one.
Soon, the clock chimed four o'clock. The door opened and children came home. Subaru immediately grasped Ai by the arm
"How about a round trip, Ai-chan? Just the two of us. We're going to see uncle Bourbon.
Yes, he thought. Bourbon must have already found out from Mouri's, so the only way to protect Ai was to 'kill' her in front of Bourbon.
"Hold on." Conan said "You're not gonna do what I think you are?"
"Yes, that's exactly what I'm gonna do." Subaru affirmed "For my beloved's sake."
And the door closed silently, leaving Conan and Sera dumbfounded.
