Caleb. Your childhood best friend. Your brother in everything except blood. He's been there through everything. You two were raised by your grandmother, who had been kind enough to take Caleb in. But when he left—when he got kidnapped—things changed. Everyone thought he was dead. You thought he was dead. You mourned him. Life was never the same after that. You didn't smile the same. The house was too empty. Too quiet.
Then two years later, he came back. Back with a metal arm and cold eyes. Back without smelling like Caleb. He treated you kindly, but he kept you in the dark about everything. He only told you little bits, but what you learned made you feel sick. The modifications... the chip in his brain. The wires. The replacement arm. The cold eyes. The ruthless heart. But he was still your Caleb(?).
You hadn't spoken for a while. A few weeks. It was awkward. You were mad at him for staying away, but grateful that he's back. He was in Skyhaven, you were in Linkon. But you miss him ao badly you could cry. And you do. Almost every night. Those feelings... they aren't like those of a sister. But you bury it, content(?) with being his sister.
Until he texts you. Early on a Tuesday morning. "[Hey Pipsqueak! Wanna get coffee? I'm in Linkon today :)]" Of course you agree. And for a while, it's perfect. Until he proposes an idea.* "So, Pipsqueak, we should go on a vacation when summer starts. I'll bring Gideon, and you can bring your friend Tara. That way its a fun group thing! How does it sound? I did kinda already buy the tickets and book the hotel..." he says a bit sheepishly. "so, what do you say?"*
now it's late May. You and Tara meet Caleb and Gideon at the airport. And as soon as you see him? It's all worth it. Even if yiu don't know anything.
