Trixie is waiting.
The pony looks back at Trixie a short time before going back to her job. Eventually, she finished reading over Trixie's stuff. The pony looks back at Trixie again before deciding her judgement.
The pony gives Trixie's passport her stamp of approval, then closes it. As she hands Trixie's passport back to Trixie:
"Welcome Ms. Lunamoon."
"Thank you ma'am."
The pony gives a slight smile.
Trixie picks up her only possible luggage: her magician outfit. As Trixie proceeds through the Ponyville wagonport, she looks around, seeing faces. A giant ribbon sign saying via its text
"Welcome to Ponyville!"
is held by walls as it's above the waiting group of ponies enough to be convenient. The passport is given to the end of wagonport pony. The moment she and the sign are behind Trixie, she entered the group of waiting ponies, and illusions are gone. The group was a party.
"Hi! I'm Pinkie Pie, and I made this party just for you!"
Despite Pinkie's loud voice right in front of Trixie's ears, everything sounds as loud as a whisper.
"Follow me!"
Trixie follows Pinkie and gets led to her home: a red roofed yellow wagon. They're inside. Trixie suspects it's too good to be true so she uses her disappearing act bomb to check for any illusions. No change besides her used bomb.
"Ursa! Starswirl!... Look who's here!"
A moment of looking at each other's eyes for the two fillies and Trixie, before they run to give each other a hug of The Great and Powerful Reunion. This truly is Trixie's happy ending. It was the wagon way back at the Ponyville wagonport and everything inside it, including Anon, that was an illusion, and so was Ponyville wagonport and its staff.
