Season 4[]

In Ha'uoli La Ho'omoaika'i, Steve answers his front door and finds Aunt Deb there. He surprised to see her and pulls her into a hug. Deb wishes him a Happy Thanksgiving and Steve asks what is she doing here. She says it's been years since she's seen him and she figured it's high time she paid him a visit. Steve tells her she looks fantastic, she then tell him to let her have a look at him. She laughs and points out a little bit of grey hair Steve is growing and says it makes him look very distinguished. His tattoos though, not so much.

Mary comes into the living area with Joan to see where Steve got to. She surprised to see Deb. Deb is happy to see Mary and her little lamb and hugs the both of them. Mary says she didn't know she was coming, she then asks Steve if he knew Deb was coming. Steve says no he didn't. Deb says it's so great to see the three of them, and says they should sit down and catch up. But Steve says they can't as Mary and him are in the middle of a culinary crisis. Mary says they screwed up the turkey and that its still frozen. Aunt Deb says that she got there just in time then.

Steve then has to leave for work and asks Deb if she can handle to turkey. She says they've got it covered and for him to go.

Deb, Mary and Joan then go to the local butcher to see about getting another turkey for dinner. The butcher tells them they've got to be kidding as it's Thanksgiving but he'll go out back and have a look. Joan then begins to fuss, Mary tries to settle her but is unable to do so. Deb takes her, and Joan settles quickly. Mary looks on in awe and says that Deb is some kind of baby whisperer and asks her to send some of that her way. Mary the confides to Deb that she feels like she's in over her head and she's got no clue what's she doing. Deb tells her that she was winging it the whole time when she was raising Mary and it was scary. Being a mum is the hardest job in the world, but she couldn't think of anyone that was better suited for it then Mary. Mary's got a big heart, she smart and all she has to do is love Joan with everything she's got and she'll be fine.

The butcher then comes back with what looks like the runt of the little when it comes to turkeys. When Deb complains, he just points out that next time they should plan ahead. Deb sarcastically thanks him of this sage advice and the trio leaves.

Later in the day, Steve has to pick up Deb from HPD lock up, she had been arrested. When Steve arrives he asks her if she's okay, which she says she's fine. Steve then asks her if she wants to tell him what happened. She tells Steve that she needed some “grass” and how was she supposed to know that the guys she was buying from was narc. She then says she won't even be in lock up if those fascists at the dispensary had taken her card. Steve is very confused on what Deb is telling him. Steve then asks her why does she have a medical marijuana card. She tells him she has cataracts. Steve knows she lying and tells her so.

Deb then sits down and says this wasn't how she wanted to tell him this. Deb the explains her situation and symptoms she had before going to the doctor. The doctor ran a bunch of tests and found a tumor in her brain. Steve asks her how bad it is, to which Deb says it's quite bad. Steve is in shock, he sits down beside her and asks her what's the plan, and the course of treatment. Deb tells him there is none, it's to far along. Steve doesn't believe, but Deb says she's gone through all the treatment options with the doctors and they told her it would work so she hasn't done anything. Steve tells her that she can't give up and that she has to fight this. Deb tell him to listen to her, she doesn't want to spend whatever time she's got left in a hospital, getting pumped full of poison and feeling crappy all the time. Steve accepts her choice. He then figures out that's why she came to visit, to come say goodbye to them, Deb just nods. She then tells him he can't tell his sister just yet, which Steve that isn't fair to ask of him. But Deb says that she's going to do it, but she wants to find the right time to do so.

She then tells him to go back to work, she doesn't want any special treatment so she going to get booked. Steve reluctantly agrees and says he'll send someone to pick her up when she's done. Deb says to make sure he's good looking, she then tells Steve it's going to be alright.

Deb is leaving police station, when Catherine comes up to her and introduces herself as Steve’s friend. Deb doesn't believe that for a second and they both laugh. Catherine tells her that Steve has asked her to take her back to Steve's place, Deb asks if Steve told her anything else. Catherine pauses before saying she is so sorry to hear about her illness. Deb then says she's not ready to back yet, Catherine asks her where she wants to go. Deb asks Catherine to take her to the most beautiful place on the island. Catherine says she knows just the place.

Catherine takes Deb to a beautiful deserted beach. While there Deb says to Catherine that she's figures Catherine is going to be around for awhile and asks her to make sure Mary and Steve stay close once she's gone. They'll need each other even if they don't admit it. Catherine says she promises and Aunt Deb thanks her.

That night Deb greets Steve, Danny, Chin and Grover as they return from meeting the president. When Danny asks about the turkey, Deb apologizes and says Mary and her couldn't find a turkey big enough to feed everyone but she says Kamekona has offered to make shrimp casserole instead. As the group disagree about that for dinner, Steve says that he knew this would happen and he has a back up plan.

Deb the pulls Steve aside and tells him she has spoken to Mary about her condition and she really thinks that Mary needs her brother right now. As Steve goes outside to comfort Mary, Deb watches them through the glass door.

Turns out Steve's back up plan is to have dinner at the La Mariana Tiki Bar. Steve also set it up so that Nicky "The Kid" Demarco comes up to their table and asks Deb to sing the crowd a song.

Deb apologizes, but Steve says it’s okay.

He then asks about her trip, he wants to know how it was and if it was good. Deb says it was amazing. She was a little worried because she booked after her last round of chemo and wasn’t sure if she’d be up for the trip, but she says the sea air was just what she needed. She tells Steve that the treatments were rough, but her tumor in her brain is now half the size it was. Steve tells her she looks great. Deb points out that a little makeup and a good wig can hide anything.

Steve says he’s glad she decided to fight back. Deb says that he can thank Leonard for that, as he’s the one that talked he into doing the treatments. She then calls Leonard over, he was offering legal advice to another passenger.

Deb asks Steve if everything is okay, as he sounded pretty serious on the phone. Steve says he didn’t mean to worry her, but what he has to tell her it is serious. Steve tells Deb that Leonard is lying to her, he’s not who he says he is. Deb says she knows exactly who he is, Leonard isn’t lying to her, she’s lying to Steve. She was afraid that Steve wouldn’t approve if he knew who Leonard really was. Steve tries to explain that Leonard was involved with some really bad people, but Deb she he’s not anymore.

Deb says no and that she’s not going to, explaining the last time she told them they were devastated, especially Mary, and she’s not putting them through that again. Nick asks if there’s anything he can do, Deb says there’s one thing. Nicky says to name it, Deb says after she going Steve is going to need someone in his life with wisdom.
