Of Course is the 44th cutscene in Run 3, if counting the previous optional and hidden cutscenes in the game.
This is a minor cutscene.
The Duplicator and Child reach The Way Back part 7, only to see that there is a big gap between part 8. They suspect the Angel cut the part out so they can't tell people about the tunnels. The Child says that he's going to try to make the jump, which the Duplicator allows.
- The Duplicator thinks the tunnels are a secret of the government, and possibly the angel is allied with the government.
