This is once again part of Gunflame345’s story. Thunderlane and his little brother Rumble help out princess Luna who has lost her princess title.

“That was a very admirable thing you did,” Luna commented as she smiled at the two brothers.
“Yeah I’m pretty aweso-Whoa! Your Highness!” Thunderlane shouted as he turned and noticed who he was in the presence of and dropped to courteous bow.
“You do not need to bow to me, nor call me Princess,” Luna said pleasantly, causing him to raise up and stare at her. “I am…one of you now.”
“Oh yeah, I remember hearing about that,” Thunderlane recalled, confirming Luna’s suspicion that all of Equestria probably knew by now. “Umm, so what brings you to Ponyville Prin-…er,”
“Just call me Luna.”
“Uh, sure…So…Umm…What brings you to Ponyville Luna?”
“My sister, the Princess Celestia, had made arrangements for me to take residence here. Until things are finalized, I will be staying with a friend.”
“Really? Hey, you know you got your mane stuck?” Thunderlane noticed as he pointed with his fore hoof to the snarl that had trapped her.
“Yes,” Luna blushed, “I will admit I’m not used to putting on a yolk and this is the result of my inexperience.”
“Well we can fix that,” he said as he moved next to her and lifted the yolk from her neck, freeing tension as Rumble flew over and began to unravel the knot until her star filled mane was free and the she was able to slip out from under the yolk.
“You have my gratitude, er, it was Thunderlane wasn’t it?”
“Yep, and this is Rumble, my little brother.”
“Well thank you very much, and my thanks to you Rumble, I will admit you two are the nicest ponies I’ve met since I left the train. Would you mind pointing me in the direction of the library? I will be staying with a good acquaintance of mine, Twilight Sparkle.”
“We can do better than that Princess,” Rumble said energetically, forgetting that she no longer held the title. “Right Thunderlane?”
“Sure thing,” Thunderlane said slipping under the yolk, “we’ll take you there.”
