While the Director's Cut only shows the train with Leo in it when the funeral is over, the Theatrical Version also shows him making his statement in front of the committee. He says he had never been deeply involved in the case but he had important information about the corrupted system anyway. He keeps explaining he also knew he'd made a mistake but he'd paid for it and now he was hoping to become a valuable society member and that was he'd ever wanted.

Then the chairman asks him to give them the names of the conspirators. Leo names everyone who participated, Frank's name is also coming up.

Finally, he adds he was very well aware that, where he'd grown up, snitching was a no-go but too many lives had already been destroyed by the system and Leo thinks that's the reason he would never regret it.
