The rain had finally stopped. Thunder and Guardian were getting ready to take off for Tia's house. Guardian gripped onto Thunder's shoulders as he was then ready to go.

"Ready to go little guy?" Thunder asked, his voice cracking a little.

"Yeah Daddy." He replied, nodding his head.

Thunder then started to raise off of the ground, flapping his wings. They soon started to fly through Ponyville to the one house Thunder didn't want to go to. As they were flying, a song played in Thunder's head. A song called "Cry" by Michael Ortega. It played in his head as he flew through the dark, the wind blowing in his face. He finally caught a glimpse of the house. The lights were on so that meant she was home. He landed softly, trying not to hurt Guardian. He looked through the window carefully and what he saw killed him. Tia was sitting at there dining room table, with another stallion. They were laughing and having fun. Then, she said that words that shot through Thunder's heart like a harpoon.

"I love you." She said, looking into the stallion's eyes.

The harpoon stayed in Thunder's heart, making it sting with every second going by. He took Guardian off of his back and bundled him up in a blanket he brought from home. He placed Guardian in front of the door.

"Take care and listen to your mother" He said.

"I will Daddy." Guardian replied.

"I love you Guardian" Thunder said with a soft smile.

"I love you too Daddy." Guardian said with a small tear in his eye.

Thunder then started write on a piece of paper, a tear falling onto the paper. He then laid it gently onto Guardian. He walked up to the door and knocked on it softly. He heard hoof steps approaching the door and he quickly spread his wings. He blasted off into the sky watching as the door opened and Tia walked out. Thunder was then out of sight. Meanwhile, Tia looked down at Guardian. She was confused to why he was here.

"Hi Mommy! Daddy said I should live with you." Guardian said.

"O-oh. Okay. I'll take care of you." Tia responded.

She then noticed the paper and picked it up and slowly began to read it. The paper read:

Dear Tia,
I know that we're not together anymore and I understand. But, I have something important that I need to do. So, I'm leaving our little Guardian to be with you. What I must do is a priority. Do not try to stop me. You seem happy with that other stallion.
Love, Thunder Dash

Tia frowned and dropped the paper.

"Let's go Guardian." She said as she took him inside.

Now, was the time for Thunder to do the thing he should've done a long time ago...
