Editing The Murder of Sonic the Hedgehog (section)

===The Casino Car===
The detectives find Rouge and Blaze and ask the former about what she was searching for. Rouge explains that she has been looking for a treasure hidden on the train: a Fabergé Chao Egg. Blaze, who had stayed behind while Rouge looked, had deduced that the egg was hidden in the Casino Car. Rouge shows that she had found blueprints with the train with the safe code written on it, though she refuses to show it to the detectives due to "finders keepers". The two girls ask that they need their help, as the path to the egg, an elevator in the room, is blocked off by a Chao security guard. The group formulates a plan to swipe the guard's access card and get onto the elevator unseen: Blaze will distract the guard while Rouge picks the Chao's pocket for the card. Then Barry will tell the guard that there is a drink without a coaster, causing the guard to leave their post, allowing the four to use the elevator. After that, the trains mechanical arms will attack them in the elevator, so Tails tries to deactivate them while everyone else pretends nothing is happening. With the arms deactivated, they can reach the vault safely.

After executing the plan, the four find themselves in the vault. Rouge locates the vault and unlocks it, finally obtaining the egg. Rouge then reveals that there is a secret with the egg, explaining that there have been only three of the eggs in existence, each with their own secret. No one knows the secret because no one has lived to tell the tale about it. Rouge eagerly twists the egg in an attempt to open it, but it causes it to start ticking. The group becomes horrified, thinking that the egg is actually a bomb, and starts to look for options of defusing it. Barry then remembers Espio, during the quiz with the manual, telling them that the train's mechanical hands would not allow weapons or explosives onto the train for the passengers' safety. Since the egg was left aboard, it could not have been a bomb, so they let the egg keep ticking. After a few seconds, the egg opens, revealing a hidden gen-encrusted pendant of a Chao. Barry figures that the owners of the egg kept the secret until their deaths, which explains why no one knew the secret.

The group returns to the Casino Car, and no one has suspected a thing, and the guard has returned to their post. Tails ask for the blueprints now that Rouge was done was it, but she refuses again in case there is more treasure on the train. Before the detectives leave, Blaze tells them that Shadow passed by and gave them keys, like he did with Knuckles. The girls unlock the next door, and the detectives continue to the Lounge Car.
