A different sibling's wedding

As the train made it's way towards Canterlot, the ponies plus dragon all discussed their plans for the after party after the wedding. However, AJ couldn't help but notice Twilight staring out the window for some reason...

"Is everything alright sugar cube?"

"I just hope that Shining Armor doesn't feel like I abandoned him, we've always been so close."

"Who is Shining Armor?"

"He's my brother, he's the royal guard in Canterlot. He has a very important task of keeping a threat made against the capital at bay with a forcefield that only he can conjure up. And I would hate to make him feel that I put my marriage over him."

"I'm sure that he knows you'll always be there for him Twi, but I do hope things get better there..."

"I hope so too..."

Eventually, the train made it to Canterlot, as it passed through a pink bubblegum forcefield surrounding the entire capital.

When the train parked and stopped, the seven noticed all the guards surrounding the station.

"What's with all the tight security around the joint?" Dash asked.

"Perhaps they are taking extra precautions to make sure no one disrupts the wedding." Rarity speculated.

"You all take your time adjusting, but I have to go see my brother to make sure he's doing ok." Twilight stated, as she headed inside to check on her brother, leaving her friends concerned.

Meanwhile, Shining Armor was railing the troops to head to their posts.

"Shining Armor!" Twilight called from below, when the guards aimed their spears at the unicorn.

"AHEM! That would be one of the brides, soldiers." Shining affirmed his troops.

"Apologies Captain, we were very alert, but it won't happen again." A guard conformed, as they left the captain to catch up with his sister.

"Shining! I missed you so much! How is everything in Canterlot?" Twilight asked.

"Things could be going a bit better, protecting Canterlot all by myself isn't easy, and even worse, it's giving me terrible migraines..."

"Oh, I'm so sorry... I just want you to know that if there's anything I can do to-"

"No no! You deserve to relax and enjoy your special day. I wouldn't want my royal duties to become a burden to you."

"Shining, you're not a burden, you're my BBBFF. And that'll never change."

"Thanks sis." Shining Armor hugged his LSBFF tightly, which she warmly reciprocated.

"But back to the topic at hoof, how is Cadance doing? Is everything alright with her?" Twilight asked.

"Actually, I haven't heard from Cadance ever since the two of you started planning your wedding. Whatever she's doing, it must be important."

"Well I need to see her to make sure she's prepared." Twilight stated, but before one of them could say any more, they heard a hoof step near them.

"I hope I'm not interrupting anything important?"

"Oh! No, we were just talking about you, making sure you are able to prepare for your big day."

"Well of course I am. But Captain Shining Armor, can I go see your sister please?"

"Umm, ok?..."

Shining merely watched as Twilight's bride wrapped her hoof around her.

"You go on and perform your duties, while Cadance checks in on the wedding preparations. I'll be checking in on them as well to make sure everything goes as plan-"

"No, I should check in on them. You don't deserve to be stressed on your wedding day." Shining assured his sister.

"Really?... But you have to keep the barrier standing."

"I can multi task, I just wanna make sure that everything goes perfect for your wedding. Don't you trust me sis?..."

"Ok... But just so you know we are incredibly happy that you get to spend the day at our happiest moment, right dear?" Twilight asked her bride.

"Absolutely..."

As the brides left to their rooms, Shining Armor couldn't help but feel that something very strange was happening right under his nose...
