You cannot pass Argus, the Organon.

It is too bright in there. Could you make it darker?

But not dark enough to sneak past Argus. But maybe dark enough to fool him!

If you could fool Argus that you are Cletus. It shouldn't be hard as you look pretty much alike. Impersonate Cletus.

While wearing the Cletus Costume you can try to pass the guard.

Ohh.. how hard can it be? You would need to present a cartridge to Argus.

Have you talked to Cletus again?

Ask about the agreement, ask about Goal and talk trash about Deponia. Now you should be able to ask about the backup cartridge. Say that Goal is unconsciouness. You should now have the Backup Cartridge.

Try to pass the guard again.

Great job! Go find Goal.
