* this also means no Feeny calls most likely as Michael Jacobs has said Will is the only one who is really capable of doing them
Shawn: By the events of Girl Meets World, Shawn has made a name for himself as a world-traveling photographer. However, franchise creator Michael Jacobs has stated that he will not have had the same positive outcome as Cory and Topanga have. Cory's lifelong best friend since childhood, Topanga's close childhood friend, and uncle figure to Riley and Auggie. Since the end of Boy Meets World, Shawn has traveled around as a writer and a photographer. He also forms a friendship with Maya. Cory and Shawn have a very close relationship with each other that, as shown in Boy Meets World, is at times even stronger than the relationship between Cory and Topanga.
Topanga: Shortly after the Boy Meets World finale, Topanga becomes pregnant and later gives birth to her first child, a daughter named Riley. She later has a second child, a son named August "Auggie" Matthews. Cory and Topanga remain married at the time of the events of Girl Meets World, at which point Riley is 12 years old. The producers of Girl Meets World have indicated that Topanga's career is not yet certain for the revival series; original plans for the series had her abandoning her law career and operating a restaurant.
* she is a lawyer I believe.
