A video walkthrough for Phoenix Wright: Ace Attorney: Trials and Tribulations (also known as Phoenix Wright 3) for the Nintendo DS. Episode 5: Bridge to the Turnabout. Part 26 of 44.
In this part, Iris testifies, saying that she saw Maya Fey kill Elise Deauxnim in self defense. Iris' account of the deadly struggle is flawed, because she doesn't know that the real murder weapon was a sword, hidden inside the victim's staff. Furthermore, Phoenix finds it suspicious that Elise Deauxnim would suddenly attack Maya without provocation, seeing as the two of them are mother and daughter.
Godot then produces a dagger, which he claims is the real murder weapon. This convinces the Judge that, despite Phoenix's objections, Iris' story is true.
