Here's Chapter 4.

We decided to rest for the night. That was good for me cause my hooves were getting tired from walking; I wasn't use to walking such a distance, especially in this dark, dense forest. I was glad that Lone Warrior was finally warming up to me; I hoped we could become friends eventually.

I woke up the next morning expecting to see the sun up over the trees only to be greeted by darkness and unable to open my eyes. I stood up and started to panic.

"LONE WARRIOR, WHERE ARE YOU?"

I felt something touch my flank and I panicked.

"Derpy, its me." I heard the familiar voice speak to me.

"Lone Warrior, I can't see anything!"

"Thats because you're wearing a blindfold."

"You blindfolded me while I was asleep?"

I was infuriated of the thought that Lone Warrior would play such a cruel trick on someone. I felt Lone Warrior laying a hoof on my good shoulder as he attempted to calm me down.

"You wanted to know how I do all the things I do. If you want to know, then you have to experience it through my eyes."

Well I guess that made sense now that he put it that way, but he could've just told me what he was going to do instead of giving me a heart attack by putting a blindfold on me while I was sleeping. I staggered around a bit and nearly tripped on a rock, but Lone Warrior was there to catch me.

"Use the tip of your hooves to feel for small objects in the ground."

"What about big things in the way or hit up against a branch?"

"Just use your muzzle."

"My muzzle?" I asked confusingly, "Well okay, I'll try it."

I walked around a little bit, using the tips of my hooves to feel for small objects like Lone Warrior suggested. Everything my senses could pick up seemed amplified while wearing the blindfold. My nose finally touched something. It felt like a branch with ticklish leaves on it. The leaves made me sneeze.

Suddenly, my ears picked up a buzzing sound far in the distance.

"Hey, I hear a cicada in the distance!"

"Thats good." said Lone Warrior, "You're using your senses."

I smiled proudly.

"So am I going to have to wear this blindfold throughout our trip?"

"Of course not. I'm only showing you how to use your other senses."

I suddenly caught a whiff of something savory and delicious in the air. I started to follow the scent with my nose. The savory scent kept getting closer and closer. My preoccupation with the yummy smell had me ignoring Lone Warrior telling me not to go off too far, but I was so hungry that I had to find out what that enticing smell was.

Suddenly, I bumped into something hard and wooden and fell to the ground. I could hear what sounded like a door opening and then a voice spoke.

"Who is this I see at my door? A blindfolded pegasus fallen to the floor?"

I decided to take off my blindfold to see who was talking and I was met by an array of dizzying stripes. As I tried to adjust my eyes, I realized I've seen this pony before.

"Hey, I know you! You're that zebra who occasionally comes into Ponyville!"

I could hear Lone Warrior catching up behind me and as he approached, the zebra looked over at him.

"Lone Warrior, what a Celestia send, and I see you have brought a friend."

"Sorry to disturb you, Zecora; Derpy's curiosity tends to get the best of her."

"You know each other?" I asked.

"We've met before."

Zecora looked at us and smiled

"You two look tired and weary. Perhaps some hospitality will keep you from getting dreary."

"Oh thank you!" I chirped.

I was excited that somepony would let us into their home after a long trip and, from the smell coming from inside Zecora's hut, it smelt like there was food to eat. I went inside to be greeted by tribal artifacts and stacks of potions and in a cauldron, was some yummy looking stew.

"I just mixed up that pot of brew. Would you care for a bowl of stew?"

"I sure would."

I wondered if Zecora ever got tired of rhyming. What if she got stuck while trying to rhyme words like "orange"? I grabbed myself a bowl, ladled some stew, and sat down to take a bite. As I was eating, I've overheard Lone Warrior talking to Zecora.

"I'm sorry to have disturbed you, Zecora. I don't like other ponies following me around."

"The past still plagues your mind? Tis your heart that is truly blind."

"I'm sorry. I know you did all you could to help me, but I just..."

I saw Zecora place a hoof on Lone Warrior's shoulder.

"You have already made a friend; tis progress for you to amend."

"I don't need friends!" Lone Warrior took Zecora's hoof off his shoulder, "I'm better off without them and I'm better off without Derpy!"

Lone Warrior looked pretty angry pushing Zecora away. It hurt to hear him mention my name in spite, but we had just started to have a connection; maybe he was angry at something else. I didn't feel like eating much anymore and excused myself from the table.

"I think Derpy and I are ready to go."

Lone Warrior walked over to me, letting me know that it was time to go. I got up and followed him out the door.
