Emerald decides to book it back to Joyride's place.

Though invisible, he can't help but feel paranoid, glancing behind him every few steps to make sure he isn't being followed. Is it going to be like this every where he goes?

As Emerald gets close to Coursewalk, he sees the second pony who tried to kidnap him pass by him on the sidewalk, looking angry.

For some reason this makes Emerald happy, and he skips the rest of the way to #304. He decides to go to the library and pass the time until Joyride returns by studying. In between reading and resting his eyes he decides to build his book hovel up into a proper house. This is made much easier by the fact that there are some very large books in the library.

Some too large in fact. Emerald made the mistake of asking for the biggest books in the library, and was almost demolished by books three times larger than him.

His study is fruitful, and though he can't pretend to have memorized any potions, he understands how to make a few of them, such as lesser versions of the fireball potion that Joyride mentioned, as well as some basic utility potions like flu resistance, as well as healing potions that can cure small scraps and bruises.

>Knowledge of Alchemy increases!

Emerald begins to hurl a gurgle from his stomach, and suddenly realizes how hungry he is. He has a habit of forgetting to eat when he reads. Sometimes books are just so absorbing!

There is a knock at the library door, and getting up Emerald opens it to see Joyride standing there in the mid-afternoon sun.

"Hey, Hope should be coming in soon. Jeez, you haven't been studying all day have you?" Joyride says with a smirk, "Neeerd."

What does Emerald do?
