I'm stuck at the part where you're helping the actress, and you go inside her mind. I can't find the other script to lower the blimp. Can anyone help me out?

There are three scripts. The second two are hidden somewhere in the sets, but I don't think you have access to them until you've performed the previous play successfully.

I could be wrong, but...
The script you need should be on the set that has the water on the right, used by the second script. I seem to remember it being in the boat.

Hope that helps.

Thanks so much! You posted a little bit late, though... I'm already in the next level, with Edgar. Thanks alot, though!

No worries, glad you're past it. Have fun. :)
