The Midsummer Festival has been absolutely wonderful... No, not just wonderful. But very phenomenal. Twilight has never imagined, that the midsummer festival can be so interesting to celebrate. Although she didn't read any books about it (even it didn't mention any of it), but luckily she has friends who knows about it and tells her everything she needs to know.
But the festival would never have been phenomenal without Sweetheart. She was so happy that she's still here in Ponyville and the best thing about it is, that they can finally be together. Not only for assistance, but as real friends.

"Shall we bet which of us can pick many apples as possible?" Sweetheart suggested with a competed smile.

She pointed at few barrel filled with water and apples floating like small round boats on the water. Twilight accepted the challenge and went to Big Mac, who was in charge of the stall. Twilight and Sweetheart gave him each of their coin and he responded as usual with a 'Eeyup' and showed them two available barrels. Sweetheart and Twilight was ready with their head almost touching the water and Granny Smith got ready to count down, while sitting on her rocking chain and sounds a bit sleepy;

"Ready... Steady... Go!"

Twilight and Sweetheart dived their heads quickly and collects as much apples as possible. Although they almost drown in the water and their teeth can not manage to gather more apples, they just laughed and had even more fun than ever. Twilight and Sweetheart was very exhausted after trying many midsummer activities. They found a table where they can sit and relax, but they still have a good time in the evening.
"Ah... My stomach is completely full..." Sweetheart said exhausting after eating too much delights, which consists mostly of apples (their stomachs were bloated by Applejacks delicious apple desserts and can hardly eat more).
"Yes... Good thing, our stomachs didn't explode like that incantation, I experimented last week to make the oranges grow!" Twilight said also exhausted but couldn't hold her laughter by the thought of the failed experiment. But they ended up laughing all the time, while the other ponies who goes past them, stares strangely to them.
They giggled after some minutes later until Fluttrshy calls Twilight with a quiet, but a serious tone. "Excuse me..." Twilight said in hurry, but Sweetheart smiled understanding and shushed her to Fluttershy. Twilight smiled quickly to her before she runs across Fluttershy who desperately couldn't find some animals, who just disappeared. Twilight promises Fluttershy to find them quickly as possible, causing Flutterhy to smile a bit shyly (not that shy, but she just smiles like that). Twilight begins immediately to find the animals, like Fluttershy told her, had ran into the woods.

After the search of the animals, she has already found a few squirrels, four rabbits, one deer and two goats as Fluttershy told. It wasn't difficult to get them back (the deer was a challange to capture or tame it, for that matter), but Fluttershy was so happy to see her animals and thanked Twilight to have found them. She was a bit affected by Fluttershy's positive comment, but she was most exciting by getting back to Sweetheart, as she promised. She hurries back to the table where Sweetheart sits, but she was suddenly gone.
"She sneaks out again?!" Twilight thought suspicious and searched all the stalls, they have been through. She are still looking after Sweetheart in a panic mode, but luckily she found her, having a conversation with a light brown pony with a white mane and its cutie mark for four emeralds. She calls at Sweetheart and she turns frightened against Twilight, which almost looked worried.

"You can't just go anywhere like this! Have you any idea how worried I was?!" Twilight said with a severe expression.

Sweetheart apologizes for having left her, but she explained that she was bored and went for a little walk before she could get back to their table, but fell in a conversation with a young stallion named Rare Find.
They introduces politely to each other (although Twilight sees him often here in Ponyville, but have never spoken to him), and he tells what he and Sweetheart talked about how much they loves helping other ponies when they need help. Twilight nodded interested, but thought that she has never seen him help while her and others arranges the midsummer festival. Then again... She did see him helping to hoist the midsummer pole up and decorates the town, so he was right about, what he was saying.
Twilight thinks it was nice to meet him, but right now, she needs to have some quality time with her best #1 BFF. They left Rare Find and went back to their table. She asked Sweetheart whether they should try more activities orjust to hang out with her friends, but Sweetheart shook her head and said that she was a bit thirsty. Twilight can also tell that she's also thirsty and volunteers herself to buy some drinks from Pinkie's small milkshake stall.
Pinkie's stall was not hard to find. As usual Pinkie always puts balloons and confetti, so it´ll look like a birthday celebration. But it looked more like a cake wagon than a milkshake. But instead of Pinkie, Mrs. Cake was in charged and shares some milkshakes out.
Twilight ordered two vanilla milkshakes where Mrs. Cake placed them immediately. Twilight was confused, but Mrs. Cake told her that Pinkie has already made them before she was supposed to help Rainbow Dash and Cloudchaser, and Flitter to hang more candy up to the children's candy tree (a new invention, Pinkie Pie has suggested). She gave Mrs. Cake two golden coins and went back to her table with the milkshakes. But when she was at the table, Sweetheart was already gone.

"Where is she now?" Twilight thought slightly annoyed.

She leaves the milkshakes to find Sweetheart again. She asked every pony, if they've seen her around here, but nopony has any idea where she could be. Including Spike, who claims that he saw Sweetheart talk to somepony a while ago, but don't know who. Even it didn't help much, but she was happy to have a baby dragon friend, who has a good eye than others.
So she tried to ask Fluttershy, but she hasn't seen her since she had to care for the animals. She tried Applejack, but she said she was too busy to sell more apple pies.
Then she tried Rarity, who was obsessed with her new dress. "Have you seen Sweetheart, Rarity?" Twilight asks loudly from the music noise, but Rarity was too approached by her beautiful dress. She was like enchanted by the golden tulips that are finely patterned on the dress. Twilight tried again, but even then, Rarity finally woke up from her trance.
"Have you seen Sweetheart anywhere? I can't find her..." Twilight asked again, but Rarity replied with the same answer as the others. Twilight sighs annoyed, but she NEED find out what Sweetheart is doing. She quickly said farewell to Rarity and rushed away to her quest.
But then she heard a small ego, but she's too busy to focus, but then she heard a sudden call. She turns back and sees Rarity running after her with the dress, floating elegantly in the air. She looked quite winded out with so much attention from the dress, but she said shortly that she actually saw Sweetheart a few minutes ago.
Twilight felt hopeful for the good news. She asked when she last saw her and Rarity responded out of breath that she saw Sweetheart talking with Muffins and Time Turner a moment ago, before she went in the crowd and vanished.
Twilight thanks Rarity and rushs immediately to find Ditzy or Time Turner. It wasn't too long before she found Muffins with her niece, Dinky. She asked her immediately where Sweetheart is. Muffins said that she asked after her muffins as she promised and was just about to tell where she last saw her, but Twilight had too busy without question mark and left Ditzy and Dinky with a confusing expression.
She galloped through the square, and luckily she discovered Sweetheart in the crowd. She followed Sweetheart in fast pace. It almost felt like an eternity when she sometimes loses her, but she knew where she was going. Twilight was already out of the city. She finally saw Sweetheart going into the darkness of Everfree Forest.

"This time you´ll never get away" Twilight thought with a suspicious and succesful glance and went courageously through Everfree Forest.
