《脱轨》江晓媛不是穿越者，是被灯塔系统篡改了记忆。
江晓媛在寻找村支书的路上，忽然看到一些熟悉的景象，这让她回忆起了以前与祁连的故事。尽管她并不是那个江晓媛，却奇怪地能够回忆起她的记忆！在一个角落里，祁连和江晓媛发现了一个盒子，里面有一份合同。合同的甲方是明光实验室，而乙方则是江晓媛自己。祁连不得不告诉江晓媛关于明光实验室的资料，而这也许就是导致江晓媛和霍柏宇、许靖阳变成现在这种状态的原因。两人突然想起十年前，他们全班一起埋了一个时间胶囊，于是他们开始挖掘那个埋藏的地方。信中，江晓媛写下了对十年后的期望，但下一封信却是给十八岁的自己的。她在信中提到，自己由于奶奶生病，不得不去外地打工以筹集治疗费用。江晓媛感到崩溃，她回想起小时候告诉父亲自己想学画画时，父亲只是默默地沉默着。她知道家庭贫困，所以从那时起，她便有了一个梦想，在那个梦中，她可以学习画画，出国读书。但她知道，这辈子已经没有实现梦想的可能了。这封信是江晓媛签合同的前一天写的，她当时回来过！江晓媛的画中描绘着她梦中的“小公主江晓媛”，而此刻的她看到这幅画时感到非常震惊，为什么她的人生与画中的人生如此一致？祁连似乎已经有了答案，他告诉江晓媛，她并不是时空穿越而来的。然而，江晓媛不愿相信祁连所说的话，于是他们决定一起去实验室寻找真相。他们到达明光实验室后，江晓媛突然想起自己一些记忆碎片，比如她曾经偷听到灯塔实验只不过是一款虚拟游戏，并不是真实的。一旦被警觉，这些记忆就会被覆盖掉。在通道里，江晓媛发现了之前她留下的日记本，上面写着她已经察觉到灯塔系统正在篡改她的记忆，并希望如果自己忘记了一切，未来的自己能通过这本日记想起所有事情。
《脱轨》精彩剧情介绍 第26集：蒋博替江晓媛撑腰
Feng Ruixue immediately called Qi Lian after the incident, insisting that the organizers hold Jiang Xiaoyuan accountable. Jiang Bo, upon hearing this news, turned to Yue Ningchuan, who had cozied up to Fan Xiaoxiao, acting entirely under her guidance. In an effort to alleviate the situation, Qi Lian called his father to ask him to intervene with Director Xie. Today's affected actress, Xie Yi, was his daughter.
Jiang Bo rushed to support Jiang Xiaoyuan, offering compensation such as a red carpet appearance, magazine covers, and commercial endorsements for Xie Yi. For the first time in public, Jiang Bo mentioned his relationship with Fan Xiaoxiao and even called her during the event. After everyone left, Jiang Bo gave Jiang Xiaoyuan an answer: Qi Lian had guessed only half right. Jiang Bo persuaded Jiang Xiaoyuan to make a trade, suggesting he would no longer work as a makeup artist in the future. Jiang Xiaoyuan should shine brightly on her own path.
When Jiang Xiaoyuan tried to access surveillance footage, she was blocked due to the theater being funded by the Qi family. They discovered that the person who did Amy's makeup was named Mei Mei. Amy's company called, insisting Jiang Xiaoyuan not be hired. Jiang Bo's original plan did not succeed. As Jiang Xiaoyuan left, she inadvertently witnessed Fan Xiaoxiao slap Jiang Bo, feeling dizzy and recalling something about data.
As Fan Xiaoxiao and Jiang Bo departed, Jiang Xiaoyuan fainted again by the roadside. Qi Lian had her examined and found a chip at the back of her neck—a reminder from the police. They publicly announced the conclusion of the case involving Huo Boyu but secretly continued their investigation, finding a chip on him too. Qi Lian's test results showed no chip on his body.
Huo Boyu retired from the industry and revealed his relationship with Fan Xiaoxiao. It was discovered that Fan Xiaoxiao's company had huge financial loopholes; she needed to announce Noah's Ark soon. Yue Ningchuan's assistant framed Jiang Xiaoyuan, prompting him to visit her the next day. Jiang Bo revealed secrets for Jiang Xiaoyuan, facing extreme danger.
Fan Xiaoxiao adopted Jiang Bo due to an unhappy marriage, but her husband did not change his mind even with Jiang Bo, making his childhood extremely oppressive. That night, Fan Xiaoxiao used family ties to ask Jiang Bo for help. They checked her accounts every night, leaving her no way out. Qi Lian visited Jiang Xiaoyuan and shared Jiang Bo's story.
Jiang Bo's neighbor claimed he suffered severe domestic violence. When police arrived, they found Jiang Bo had fatally stabbed his foster father. He spent four years in a mental health recovery center before returning to a normal life. By then, Fan Xiaoxiao had remarried and didn't inform her second husband about Jiang Bo's existence. Jiang Bo's academic career was also troubled.
However, Jiang Xiaoyuan remained grateful to Jiang Bo and didn't want him implicated. Qi Lian found someone who knew about the Ming Guang Laboratory, saying Noah had died five years ago. The Lighthouse system left behind some incomplete data; Mammoth Games now copied the Lighthouse project. The informant told Qi Lian that Noah's real name was Xu Jingyang, a Chinese-American adopted by a white couple. Despite searching for so long, Qi Lian was still in pain.
To further investigate, Qi Lian took Jiang Xiaoyuan to interview Fan Xiaoxiao. She resisted Jiang Xiaoyuan's arrival and didn't want them to see Jiang Bo. Qi Lian exposed Fan Xiaoxiao's old secrets: Perhaps young Jiang Bo, at just ten years old, was merely a scapegoat for Fan Xiaoxiao's husband's murder.
