Throughout the Series[]

Season 1[]

In a flashback, Kat was throwing her going-away party at what is described as Hannah's 1st house. She and Hannah bet against Clay, and Kat ended up owing Hannah five dollars when Clay entered the party. She welcomed Clay and handed him a beer. When she saw Bryce flirting with Hannah, she told Hannah to stay away from him. After Hannah went away to get a beer, she told Clay to make a move. At the time, she was dating Justin, although Hannah clearly liked him. After she moved away, Kat video chatted Hannah and told her that he is all hers.[1]

Kat returned back when the Bakers handed out subpoenas for their lawsuit, since Kat was on the list that Olivia found in the back of Hannah's closet. When she arrived at the taped deposition, Kat made it clear the boys, specifically jocks at Liberty High are disrespectful and believe they can do whatever they want to girls. Dennis stated that Kat texted Hannah more than once that she had a bad taste in guys and Kat then claimed that if she hadn't moved away, she wouldn't have let Hannah date Justin and she would have been around to help her through the pain he and others caused her and that Hannah would still be alive today. When Dennis asked if she was talking about Justin Foley, she stated that Justin is dead to her.[2]

She is not seen or mentioned again.


Although she has only appeared on two occasions in the series, Kat is shown to be a kind and caring person and is the only true friend that Hannah ever had and was shown to care for her deeply. Like Hannah she is shown to have a witty sense of humor and is very kind towards Clay and encouraged him to go after Hannah.

Kat is shown to be well aware of the cruelty of many of the boys at Liberty High as she warned Hannah to stay away from Bryce at the going away party she discovered Bryce and Hannah flirting with each other. She describes Justin, her boyfriend at the time, as sweet but an idiot. After Kat moves away, she continues to communicate with both Hannah and Justin however both state that its not consistent basis. Kat was unbothered when Hannah confessed over a video call that she liked Justin and told Hannah she could have him, referring to him as "jock crack". She later regrets that she allowed Hannah to date Justin, which unfortunately was the beginning of the chain of events that would ultimately end in her friend's death by suicide.

During her deposition Kat strongly expresses her disdain for the treatment suffered by girls at her former school and is shown to be utterly devastated by her friend's death and claims that had she not moved away and allowed Hannah to pursue Justin, she would still be alive. Kat blamed herself for Hannah's death to a degree and regrets not being there for her when she needed help. She make it clear that she now hates Justin and that he is dead to her.

Meet the boys. Justin Foley is mine, and Zach Dempsey for you.
— Kat introducing Hannah to Justin and Zach in "Tape 1, Side A"

The jocks, they walk the halls like they own the place. The teachers feed into it. Bolan feeds into it. It's just it's how it is. (...) I mean you try going to school with a bunch of Neanderthals who are told they are the only thing of value at school, and that the rest of us are merely there to cheer them on and provide them with whatever support they need.
— Kat about the jocks at her deposition in "Tape 7, Side A"
