She was a tenacious Assistant District's Attorney who plays with people's weaknesses to get what she wants within Manhattan's DA's Office. When Katrina meets Harvey, whose reputation is "a legend" at the office, she acts tough and says that she wants to take him down. She then reveals to Mike that she was merely trying to impress him because she wants to "make the same career jump Harvey made", which is to a position at Pearson Hardman. She then takes their deal to try to appease Harvey.
Although Harvey had no intention of taking her in initially, he later bribes her with a position if she does not take Mike's information into consideration for the felony hit-and-run case against their client, Liam Colson.
Now a senior associate at Pearson Hardman, Louis Litt confronts her and later tells her that she will be under his tutelage to appease for his loss of an associate, much to Katrina's displeasure. She approaches Donna for advice about him and is told to take Louis on. She and Louis then begin tricking each other regarding a case with a very punitive judge. In the end, after Katrina gets Louis arrested, they call a truce.
Having experience from the DA's office, she uses it to pull rank over the other associates, particularly Mike and even Rachel, for being a paralegal. Using shrewd tactics and below the belt moves, she takes credit for Mike's idea by delaying Rachel from helping Mike, and and it to Harvey just a step ahead.
At the end of the season 4 mid season summer finale, she resigns from Pearson Specter to avoid being fired by Jessica after she told ex-employee Louis Litt about Harvey's problems with VersaLife.
