"A Sonic Rainboom was a legendary move that hasn't been seen for a long time. But then when I was a filly, I made history by doing a Sonic Rainboom, which is caused when I go so fast, I break the sound and light barrier one after another, going from speeds of Mach 5 to Mach 10, in like half a second." She said, before noticing mostly everyone was staring at her as to how she known this. "...Twilight told me the speed part." She said, blushing.
Rainbow Dash smiled. "Ah it was nothing. Being honorary family members, we felt the need to help out in anyway as we could." She said.
"Ahn don't worry sis, I have an idea that would be perfect for an ending of the reunion, It should make it very memorable as it has never been done before!" Apple Bloom said to Applejack. "Well at one of our Reunions that is..." She added
Rave and Sweetie Belle stood next to each other, as Rave looked around the farm in curiosity.
Applejack rubbed the back of her head. "Well...Ah'll give a listen, my other attempts tah make it memorable didn't quite go accordin' to plan. We still had a good reunion in the end though. What's the idea?"
"Well, tha subject of the Sonic Rainboom came up, and tha idea came up to have Rainbow over here do tha Sonic Rainboom while our relatives are leavin'" She said with a smile. "And since we all wanna see a Rainboom, we thought that this might be a good place tah do it" She added.
Rainbow stepped forward. "I know you told me to stop practicing over your field when I was trying to do the Rainboom in the first place, on account of me running into your trees and stuff, but since I can do it on command, im certain I won't mess up this time." She said, rubbing the back of her head.
Applejack gave it some thought. "Well, Ah can't say that wouldn't be amazin', but let meh check with the family first," the farm pony said, walking over and seeing if they'd be alright with it. "Ok, they're fine with it," she replied, looking to Rainbow. "Where yah gonna do it so they know where tah look?"
Rave stood next to Ladybug and Babs. "Bet ya what we do while down here would probably never happen in Manehatten" She said, watching for the Rainboom.
Sweetie Belle and Apple Bloom followed suit, ready to see it.
Rainbow Dash saltuted and hovered up. "It will be just like the Wedding, but alot more better and cooler." She said, before taking off to the back of the farm. Rainbow waited untill she saw the dust cloud, signaling the movement of the family. Smirking, she took off at full speed for the exit, the cone already forming around her body. She grit her teeth as she push foward, fighting the barrier as much as she could. Just before she hit the exit, she angled herself upwards as she felt her body slip through the barrier and began to propel forward...
Boom. That what all Rainbow had thought as she shot forward, a Rainbow trail behind her, and a massive Rainboom surrounding the sky, big enough that all of Ponyville and then some would have seen it.
Rainbow Dash cheered as she looked behind her. She absolutely loved the feeling of speed. She came around for a pass, and flew over the waving relatives. She smiled, happy they liked it.
Sweetie Belle smiled. "And that my friends is the Sonic Rainboom." She stated, happily watching.
Suddenly, Plum Seed came running up to the group, before stopping next to them, seeing the Rainboom. "Well, at first I was going to ask what was going on...but I think I see it now." She said, smiling at the sky.
Apple Bloom smiled. "Thanks sis, but we wouldn't have had it ifn' weren't for Babs ahn her friends." She said, motioning to them. "They mostly came up with the idea. We just agreed and followed through." She added.
Rave shook herself out the trance and smiled at the mention of her and her friends. "And I'm pretty sure we thank you. We wouldn't have been down here if you hadn't had made friends with Babs, and had her find us to make the Manehatten branch." She said to them.
