sometimes, when trying to unlock other options, you have to play through a couple levels right after that, in order to lock in the pathway.

i just figured it out! So, you have to write about the hospital in 1-2, then tackle corruption with her in 1-12, then use her in 3-7 and then replay 3-10, 3-11 and 3-12, then she will help you in 3-13
