She was present at the ED in August 2015 following an incident in a club where a man was shot. In January 2016, she was called to the scene when Noel Garcia was attacked in a park in Holby. During this time, she met them at Holby City Hospital's Emergency Department where she took a witness statement from Big Mac about what he saw. She then left in her car promising that they would catch the person responsible for the attack.
The following month, she was on a stake out for Mercedes Christie who was selling drugs in public. Mercedes was admitted to the ED after a fall, and Mercedes suspected that her and Big Mac knew each other by the way they interacted with each other. Upon further investigation, Kate found out that Mercedes' DNA was found at the scene of Noel's mugging. Big Mac was brought into the police station for questioning, and was told off for wasting police time for not telling them sooner.
