April starts running Second Time Around.
April inherited Second Time Around from her father when he died. After it came into daylight that Aprils boss Baxter Stockman was a madman and was imprisoned from his crimes against New York City, April stopped being computer scientist and started running Second Time Around. When the Shredder comes back in Teenage Mutant Ninja Turtles 9 (in story Silent Partner), the Turtles meet him in Second Time Around and battle him there. It is burned down after the battle with the rest of the building. April takes it very hard, because the building and shop were everything she had.
