Been a few days since Twilight invented the Friendship Mobile with the help from her friends and sure enough things turned out okay in those few days Twilight got word that her sister in law Princess Cadence and her brother, Shining Armor as their baby is about to be born and Twilight is starting on working Starlight's first friendship lesson which is reuniting with Sunburst which doesn't look good for Starlight, but yet tries to look her best to make Twilight proud.
at the crack of dawn the girls plus spike went to the train station but unfortunately they arrived late as they left so many gifts behind so they thought taking the hot air balloon but unfortunately somepony took it hours earlier.

"Great not only we missed the train, but we got no hot air balloon" said Twilight in frustration.

"What are we going to do now" Fluttershy questioned.

Rainbow Dash got an idea and spoked.

"Hey why don't take the car to the Crystal Empire"

"Rainbow Dash i don't think it's a good idea what if ponies get scared or even worse we won't get there in time" says Starlight in worried.

"Besides what makes you think we can get there in time, Dash?" said Applejack.

"Simple we just fly fast and get there no time flat besides we don't have any other option" Dash exclaimed.

As much she hates admitting it, but Rainbow Dash has a point and it's their only way to the crystal empire now so Twilight took a sigh and looked at the car parked in front of her castle, walked up next to Rainbow.

"As it pains me to say it but Rainbow is right, we have no other choice" Twilight said.

the girls looked at each other and give a nod full knowing that the Friendship Mobile is their only way to the crystal empire, they all walked towards the car with Pinkie, AppleJack, Rarity, Starlight in the backseat with Twilight, Spike and Fluttershy in the front with Rainbow Dash in the driver seat despite Applejack and Starlight having doubts about the Pegasus driving.

"Ok Everypony and here we go" Rainbow Dash said in a upbeat tone as she started the car and started fly up in the air becoming Airbourne and flew over Ponyville, heading north towards the crystal empire, following the train tracks to the crystal empire.

"Is it me or do i hear a chugging sounds, Darling" Rarity spoke in a bit of worry.

"Ehhh it could be wind-" Rainbow Dash was about to finish her sentence until Twilight interrupted.

"Ummmm Rainbow" Twilight points at the side mirror showing the view of the train chugging up behind them which made the girls scream in panic causing Rainbow to jerk the wheel to the right, doing barrel rolls in the sky above the train as the girls scream, Fluttershy and Spike reacted by grabbing the wheel, correcting the car and stopping the Barrel rolls as it flew over the train.

"Ok maybe i could be wrong" Rainbow spoke out of breath

"You Think?" Said Starlight as she is recovering from the barrel rolls as the car keep flying towards the Crystal Empire as Pinkie Pie give out cupcakes to everypony in the car and by the time they reached the crystal empire they land the car next to the train station waiting for Shining Armor and by the time he arrived he did look tired, but he got shocked to see his sister and her friends arrived in a car instead of taking the train.

"Twiliy?!?!" Shining Armor said in surprise.

"Hey Shining ummm long story but uhhhh are you ok?" Twilight explained as Shining Armor as he is half asleeped.

"i feel fine minus the fact i had to keep the baby asleep and now i feel amazing" Shining said with a grin on his face.

"Oh right sorry Starlight we might have-" Twilight was going to say her sentence until Spike speaked up.

"Hey Twilight why don't i take over the Friendship lesson with Sunburst and help Starlight" Spike said with a upbeat tone in his voice unaware that Starlight facehoof herself in the face.

"Actually that's not a bad idea Spike" Twilight said with joy.

"Yeah it's going to be fun yay" said Starlight as she knew that there is no point on stopping the friendship lesson.

Spike went with Starlight to Sunburst's house while Twilight, Shining Armor and the girls went to the castle in the car and by the time they got there, they were shocked to see not just Cadence, they saw Princess Celestia and Princess Luna in the baby room where they finally see baby flurry heart, but what happened next is very shocking as they see that Flurry spread her wings revealing herself as a Alicorn.

"WOAH SHE'S AN ALICORN?!?!" said Twilight in shocked reaction as the girls had their jaws dropped to this reaction.

"indeed she is and it is quite rare to be born as an Alicorn" said Celestia.

"but we thought the only way to become an Alicorn is by doing a worthy princess deed" said Rarity in confusion.

as the Princesses were about to say something flurry heart sneezed which triggered her alicorn magic causing a laser through the ceiling which made a hole as ponies above look down to see where the blast came from.

"you do know that there is no turning back on the crystalling if you wish to continue this?" said Luna with a bit concern.

Cadence hugged her baby daughter and look at Luna and Celestia with a reassuring smile.

"I know and i do wish to continue this, it is the crystalling after all" Said Cadence.

everypony nodded, all knowing that the crystalling must go on and with Cadence going with Celestia and Luna to make a speech to the Crystal Ponies while AJ, Rainbow, and Rarity helped to get Shining Armor to get ready, meanwhile Twilight stayed with Fluttershy and Pinkie with flurry in the baby room watching over her which made Twilight Questioned does Celestia know that She and her friends arrived to the Crystal Empire in a Flying Car since they missed the train, but she knows that the Princess is going to find out eventually.
The Girls were reunited as Shining Armor finshed getting ready and Cadence finishing her Speech Twilight, Fluttershy and Pinkie arrived with Flurry however things got a haywire as soon Cadence removed flurry from pinkie pie, Flurry started to tearing up and let out a loudest cry which broke the crystal heart into pieces which made everypony gasped in horror.

"This is bad, without the Crystal Heart, the Crystal Empire is going to be covered in ice and snow" said Twilight in a worried state as the Crystal Heart is Destroyed.
