Have you escaped from the cell already?
The terminal is missing the Yrk. Hmm.. and the replacement Yrk needs... Yrk! Who designs these things? If there was just an extra Yrk somewhere...
Oh yeah. At the editor's office at Porta Fisco. Use Middle Rufus. You don't believe it, but getting Toni back is essential for this.
Yeah, if you did everything right, the paperplane with Yrk should be up here now. Get it from the wall and attach it to the terminal. You can now order more Yrks!
