The magical dome that Shining Armour casts over Canterlot looks exactly like the one that Twilight put over her library in "Ponyville Confidential."
This is the third time Rarity is seen wearing her designing glasses. The other times were in "Suited for Success" and "Sweet and Elite".
During Twilight's flashback, she can be seen taking her Smarty Pants doll out of her toy box when Cadance comes into the room.
Princess Luna makes a cameo appearance in this episode.
Twilight: Maybe I was being overprotective. I could've gained a sister. But instead...I just lost a brother. (Sings) He was my big brother best friend forever! And now we'll never do anything, together.
Twilight: (Singing BBBFF)
When I was just a filly, I found it rather silly,
To see how many other ponies I could meet.
I had my books to read, didn't know that I would ever need,
Other ponies to make my life complete.
But there was colt that I cared for
I knew that he would be there for me.
My big brother, best friend forever!
Like two peas in a pod, we did everything together.
He taught me how to fly a kite.(Best friend forever!)
We never had a single fight.(We did everything together!)
We shared our hopes, we shared our dreams
I miss him more than I realized.
Rest of Mane Six: Your big brother, best friend forever
Like two peas in a pod, you did everything together.
Twilight: And though he's, oh, so far away,
I hoped that he would stay,
My big brother best friend
Fluttershy: (About Cadance) She did raise her voice at one of my birds during rehearsal.
Twilight: See? Rude!
Fluttershy: But he was singing really off key. (She takes out the bird and it starts to sing off key)
(During Twilight's flashback)
Young Twilight: I am so lucky to have you as my foalsitter.
Young Cadance: I'm the one who's lucky, Twilight.
Young Twilight: You're a princess. I'm just a regular old unicorn.
Young Cadance: You are anything but a regular old unicorn.
Twilight Sparkle: I'm still pretty ticked you're marrying somepony I don't even know. When did you even meet this "Princess Mi Amore Cadenza"?
Shining Armor: Twily, "Princess Mi Amore Cadenza" is Cadance, your old foalsitter.
Twilight Sparkle: Cadance? As in the Cadance? As in the greatest foalsitter in all the history of foalsitters?
Shining Armor: (Chuckles) You tell me. She was your foalsitter.
Pinkie Pie: I think this reception is gonna be perfect, don't you?
Princess Cadance: Perfect... if we were celebrating a six-year-old's birthday party.
Pinkie Pie: (gasps) Thank you!
Rainbow Dash: Whoa! What's with all the guards?
Rarity: I'm sure they're just taking the necessary precautions. Royal weddings do bring out the strangest ponies.
Pinkie Pie: Aaaahhh-chooo! (sneezes confetti)
Spike: So you all get to help with the big fancy wedding, but I'm the one who gets to host the bachelor party! I have just one question: What's a bachelor party?
Princess Cadence's full title, Princess Mi Amore Cadenza, is Italian for "my love cadence."

Actress Tori Spelling appeared in promotional events for this two parter and even appeared in promos for these episodes when they first premiered. She was also suppose to host a "bridal shower" event in Culver City a week before the episodes aired, but had to cancel due to pregnancy sickness and was replaced by Brooke Burke.
The wedding that took place in this episode was mentioned in the wedding section of The New York Times on April 13, 2012.
In a New York Times advert for this two parter, Princess Cadance was mentioned to be Princess Celestia's niece.
The female pony who Cadance puts under her love spell during Twilight's flashback is the OC pony of Sabrina Alberghetti, the show's storyboard artist.
This episode revolves around Twilight.
Shining Armor's mane color uses the same base and trim colors as Megaman's armor from Megaman NT Warrior. In addition, both Shining Armor and Megaman are voiced by Andrew Francis.
