Apollo Justice: Ace Attorney Trilogy

There are two conversations where Trucy's allowance is discussed, both are in Apollo Justice: Ace Attorney Case 3 - Turnabout Serenade.

The first is unmissable, as Trucy will tell you that she had to save multiple months of allowance to be able to afford some merch during the opening for Case 3.

The second is in the Investigation - Day 2 stage of the case. When in Lamiroir's Dressing Room, examine the speaker above the door to learn about how much Trucy is given per month.
