|“|| "Are you gonna torture me, or are you just gonna talk me to death?"|
"Oh, sweetie, I don't- I don't wanna torture you. I just... wanna catch up. Remember all the fun we had together?"
"Like the time you burned my family alive?"
"No, I was thinking more about the hot, crazy sex we had. But the fire thing? Yeah, that was fun, too. I love how much you hate me. Remember how this felt?"
Derek met Kate as a teenager a short time after his high school sweetheart Paige Krasikeva died from rejecting an Alpha's Bite sometime after Paige's death but was still in high school. Kate, hiding the fact that she was a member of the Argent Family and a Werewolf Huntress, seduced Derek, taking advantage of his youth and grief in order to gain more information about the Hale Family under the guise of engaging in a romantic and sexual relationship with the young man.
In late 2004 or early 2005, Kate and a number of cohorts set the Hale House on fire, killing Talia Hale and the rest of the Hale Family (including both Werewolves and Humans alike) with a few exceptions: Derek and his older sister Laura, who were at school; Cora Hale, who, believing her whole family to be dead, excaped the house and went on the run; and Peter Hale, who was so badly burned that his body became comatose to help speed up the healing process. Derek and Laura ultimately fled Beacon Hills and went to New York, where they would stay for the next three years without any news or contact with Kate or the other Argents.
In 2011, Derek returned to Beacon Hills shortly after Laura was lured back by news of a spiral burned into the corpse of a deer, where he found his sister cut in half in the woods. It wasn't long before the Argent Family, who had also recently relocated to Beacon Hills, found out that Derek was there, and, unbeknownst to Kate's brother Chris Argent, Kate and a pair of fellow Hunters came to the Hale House ruins in an attempt to get information about the new Alpha in town, where she revealed that, while the Argents weren't responsible for Laura's death, they were responsible for cutting her body in half so she couldn't heal as per their tradition.
Kate continued to manipulate and taunt Derek while attempting to convince Chris and his wife Victoria Argent to go harder in killing Derek after learning that the Alpha was Peter Hale, who had recently recovered from his coma and immense burns after killing Laura and taking her powers. However, in the final battle, Kate was killed by Peter in front of Derek, Chris, the new Beta Werewolf Scott McCall, the young Huntress Allison Argent, and their two friends, the human Stiles Stilinski and Jackson Whittemore.
However, unbeknownst to anyone at the time, Kate's throat had been clawed out so deeply that, though she was dead for a time, her body ultimately resurrected itself as she transformed into a Werejaguar right before the full moon. When she was unable to control her transformations, she got the idea to capture Derek and perform a Age Regression ritual in order to revert him to when he was a teenager and still trusted him so she could once again manipulate him into helping her; in this case, it was to obtain the Triskelion Medallion, which she believed was a supernatural talisman possessing the power to help her control her shifts. Whether intentional or accidental, this ritual also caused Derek to temporarily lose his Werewolf powers, though he ultimately learned it was actually a revolution into a Werewolf with advanced shapeshifting abilities. Upon this evolution, Derek, in full-wolf form, attacked Kate, weakening her considerably. Kate has since gone on the run, and Derek has left Beacon Hills to travel, causing the two to be separated for the time being.

- Derek and Kate's relationship is often compared to the relationship between Scott McCall and Allison Argent as part of the show's ongoing theme about history repeating itself.
- Both relationships involved a young Werewolf (Derek and Scott) getting into a relationship with an Argent Hunter, though Derek was unaware that Kate was a Hunter while Scott knew that Allison's family hunted Werewolves.
- Both Allison and Kate spurned the original Hunter's Code, "We hunt those who hunt us," with Kate ignoring the Code and killing Werewolves and other supernatural creatures indiscriminately, and Allison choosing to make a new, more benevolent Code, "We protect those who cannot protect themselves."
- Derek and Kate's relationship was the first romantic relationship to be shown for either character in the series.
