"Reminiscing ~ Scars Carved by Fire" is a Reminiscing-style music track in Phoenix Wright: Ace Attorney: Justice For All, namely the game's second case, Reunion, and Turnabout. It appears on the Gyakuten Saiban 1 and 2 Original Soundtrack and Gyakuten Saiban Sound BOX soundtrack albums as track 19 on disc 2.
This theme first plays during the case's prologue, when Ini and Mimi Miney's car crash is shown taking place. After the crash, a short speech is said by an unknown figure, sitting on the ground away from the wreckage watching the burning car. This figure is later revealed to be Mimi. The music continues to play whilst Maya Fey and Phoenix Wright are in the detention center talking about the murder, with Wright trying to console Maya, who believes her own guilt. Fey is in denial of her innocence and her friend is trying to make her think otherwise.
The theme also plays at certain points when Wright and Pearl Fey discuss the car accident and when "Ini" (actually Mimi after reconstructive surgery) talks about why she thought Turner Grey was the cause of "Mimi's" death. "Ini" would often repeat the short speech from the prologue as if she knew it by heart.
The theme plays for the final time at the very end of the case. Wright and Mia Fey discover Mimi's secret, who reveals that Ini was the one who died in the crash. This was a secret that she was going to take to her grave, so she could forget Mimi and her old life and continue her new life as Ini instead. She explained why she had taken on her identity, to try to relieve herself of her painful memories caused by the malpractice incident and Ini's death. She decided that all she had to do was pretend she died that night and taking Ini's name and face was the only way to try to start afresh.
