Brother, Meet Sister

Part 1
It was your typical, hot summer day for stepbrothers, Phineas Flynn and Ferb Fletcher. Yep, nothing exciting going on. At all........ Until a surprise visitor came... Candace Flynn, Phineas and Ferb's 15 year-old sister was watching TV with her best friend, Stacy in the living room until the doorbell rang. Lawrence and Linda were too busy to get it, so Candace got up to get it. When she opened the door, a girl with long, golden hair and gray eyes stood outside the door. "Hello", said Candace. "Hi. Is Lawrence Fletcher here?" the girl asked. Candace heard some British accent in her voice. "Uh, sure... Dad!" Candace yelled. "What is it, Candace?" Lawrence yelled back from the garage. "Come here for a sec!" the teenager said. Lawrence eventually came to the front door to stand beside his stepdaughter. "Yes, Candace- oh, hello", he said to the girl. The young girl didn't say anything, instead just showed him a picture of him, his first wife, the girl, and Ferb. Lawrence stared wide-eyed at the picture for a moment, then looked back to the girl. "Lana?" he finally said in a quiet voice. "Yes... it's me", the girl said then they both hugged. Candace was very confused now. "Wait, wait, wait, wait, wait a minute here!" Candace said. "Who is she exactly?" Lana looked confused now. She thought Candace knew who she was. Then Lawrence explained, "Candace, this is my daughter, Lana... Ferb's sister".
