In the years that followed, Minuette traveled regularly back and forth between Ponyville and Canterlot, as she and her friends Lemon Hearts and Twinkleshine visited their friend Lyra Heartstrings on a regular basis. They and Lyra rapidly became friends with Bon Bon, an Earth Pony mare who had once worked for the Equestrian Monster Capture and Containment Agency, more commonly abbreviated as EMCCA.
During this time, Minuette drew the attention of Doctor Hooves, more commonly known as simply "the Doctor", and his adopted daughter Derpy Hooves. The last known member of an enigmatic race known as "Time Lords", the Doctor had access to the TARDIS, the last surviving machine capable of time travel. The Doctor discovered that occasionally strange bubbles in the fabric of space-time would appear in Equestria, only to disappear after a highly variable period of time. Intrigued, the Doctor mounted an investigation, discovering that Minuette was at the root of most of the anomalies.
But not all of them.
The origin of the anomalies not created by Minuette lies in the strange occurrence known as the Failed Universe Merger Event, more commonly abbreviated as FUME. While many details about the origins of the event remain classified, what is known about the event itself has been public knowledge since a century after the event. Now, due to the painstaking work of physicist-turned-historian Full Glass, the answer to the anomalous space-time bubbles - as well as some of Equestria's other mysteries - has been revealed.
During the event, Alternate Equestria's versions of Minuette - known as Colgate, due to her profession as a dentist - and Lyra Heartstrings were having a small get-together in one of Alternate Canterlot's cafes. When the event occurred, Colgate attempted to use her time-altering abilities to ensure that she and Lyra stayed with their home time-stream. However, because there was no Princess Celestia's School for Gifted Unicorns in Alternate Equestria, Colgate had less experience with her abilities than Minuette, and she mistakenly latched onto the wrong time-stream, stranding her and Alternate Lyra in our universe when the universes re-separated.
Due to the trauma that the event caused to the space-time continuum, Colgate was unable to directly teleport herself and Alternate Lyra back into the middle of the event. With practically no knowledge of our Equestria's history, Colgate decided to travel back in time to before the event with Alternate Lyra, and also to learn as much about our culture and history as possible.
Traveling back in time, the pair enrolled at Canterlot High School, entering as freshmen during the sophomore year of the much-celebrated royal couple Shining Armor and Princess Cadance, who were then as yet unaware of where life would take them. This has caused much trouble for past historians, as, for reasons still unknown, Colgate enrolled under the name "Minuette".
A controversial theory aired recently by the eminent historian Field Test shortly after the origins of 'the second Minuette' and 'the second Lyra' were finally uncovered states that Colgate's use of the name Minuette was not because it was a nickname for young Colgate, as most historians have proposed, but because Minuette met with them and urged them to use matching names to help them stay inconspicuous in our world. This theory has come under heavy criticism from other historians, who have pointed out that there is little to no supporting evidence for this interpretation of history. Nevertheless, despite numerous attempts to 'debunk' it, the theory has yet to be disproved.
Where Colgate and Alternate Lyra went to after their graduation remains uncertain, though reportedly the pair parted and went separate ways. Alternate Lyra supposedly embarked on a quest to find artifacts of human civilization deep in the Saddle Arabian desert, and Colgate purportedly met up with Minuette and would stand in for her at the dentistry whenever she was busy. Though unconfirmed, the rumors provide a tantalizing glimpse of what happened to them. After that they disappear entirely - not even rumors about what happened to them remain - or why - which has generated much speculation about their fate.
But Minuette's life continued on, with her life only occasionally interrupted by drama. One of those incidents happened at the Summer Festival of 2005 AU, where she created a stable wormhole through time and space. Big Macintosh accidentally wandered into the timewarp, and Minuette followed in order to bring him back.
The only details of the trip that are known is that they landed sometime in the future and saved Ponyville from an invasion of what Big Mac called 'mutant apes'. Minuette and Big Mac returned five minutes before they arrived, and ten minutes later Minuette closed the wormhole. Speculation has emerged that the 'mutant apes' may be humans, but it remains pure conjecture, with no evidence.
Then in 2007 AU, Princess Twilight Sparkle made a surprise visit to Minuette, who reunited her with Lemon Hearts and Twinkleshine. After attempting to reconnect with their old friend Moondancer unsuccessfully a number of times, they finally convinced her of her self-worth, and became close friends once more, beginning a new chapter in the life of Minuette, who still had the majority of her life before her.
