Au where right was galeforce and dmitri's son but was kidnapped by wilford when he was a toddler as a way to get the two off the toppats back. Wilford didn't really care about the kid he was now responsible for so he pawned him off to his second terrence to care for.
Terrence took to the red headed child pretty quickly, although he did ask alot of the more experienced Toppats parenting tips because he was basically a new parent.
But Terrence started feeling guilt, especially when Right asked when he could see his dada and papa again. And with Wilford showing he only cared for the clan more then his relationship, Terrence decided to leave the Toppats with Right, leaving his hat and wedding ring behind.
After figuring out where Right's real dads lived, Terrence reunited the happy toddler with his family. Galeforce then offered Terrence a deal, he spills everything he knows about the Toppat clan and in return would not only be pardon, but become Right's honorary uncle.
Terrence told all, handing Dmitri his set of cards and keys on his keychain, that also had a sparkly squishy purple hat keychain that Terrence used as a stress ball, and passwords to as many things he could remember. Galeforce kept his end of the bargain and soon Terrence was starting his new life, working as a chef in a nearby restaurant and getting to babysit Right whenever Galeforce and Dmitri needed a babysitter.
The Toppats are eventually arrested despite Wilford's best efforts and Right grew up to be simple computer repair guy, just enjoying being close to family while still being able to live his life.
