The Murder on the Choo-Choo Train quest has an interrogation process that involves Quirky Gordon. The interrogation is about Gordon’s connection with Liora. When you start questioning Gordon, he will try to weasel out of the questioning by presenting a whole new fabricated story contradicting the evidence in our possession. To catch Gordon on the lie, you must present two sets of proper evidence to win over the interrogation in Infinity Nikki.
Quirky Gordon Interrogation First Question
“Why did you give false testimony to Liora? Tell me, what’s your connection to her, and to the missing suitcase?!“
Quirky Gordon will start claiming that he doesn’t give out fake evidence. Gordon will claim that after he applied Dawn’s First Light detergent on the fabric, he saw Piecey arranging the venue at the Barrel Home. Here, present the evidence: Mr. Leon’s Testimony about “Dawn’s First Light”
This evidence will show another side of the story from Mr. Leon’s perspective. He also saw Liora, but it was near the scene of the missing suitcase! not next to the Barrel Home.
Quirky Gordon Interrogation Second Question:

First evidence will help Nikki find a loophole in Quirky Gordon’s answer. Nikki will have a follow-up question by asking Gordon, “Maybe you never saw Liora that day at all. Maybe… you just wanted to give her a fake alibi!“
Quirky Gordon will go into defensive mode and question Nikki’s trust in Mr. Leon, throwing attacks on his character. Here, we can use two forms of evidence to put further pressure on Quirky Gordon; both evidence we are planning to use have one thing in common: they show a link between Quirky Gordon and Liora.
Evidence #1
Present the evidence: “Letter Fragments Between Quirky Gordon and Liora“
This written document reveals the connection Quirky Gordon shared with Liora. Nikki will then ask Quirky Gordon for an explanation, or she will hand Gordon over to Jenny for the missing suitcase.
Evidence #2
Here we use the evidence, A Photo of Quirky Gordon Meeting Liora.
Here we present a picture that shows Quirky Gordon meeting with Liora.
It doesn’t matter what evidence you present; both trigger the same dialogue from Quirky Gordon. One acts as a legalized document that has both Liora and Quirky Gordon; the second one shows a picture of both meeting together.
With that, the interrogation of Quirky Gordon in the Murder on the Choo-Choo Train quest is over. Now you proceed to the next line of the objective for the quest. in Infiite Nikki.
