Kate sees Tom and tells him she's homeless again and he takes her to a homeless shelter. She is not impressed and says, "Thanks Bono or Mother Teresa or whoever wins the moral superiority prize." When he tells her he volunteers there, she replies, "Christ, why don't you just get "saint" tattooed on your forehead?" Kate is obviously not "homeless" because she does have her parents' house if she needs a place to sleep and we see her go there when she doesn't have any other options. When she's trying to find Tom, who she hasn't heard from or seen in a couple of days, she goes to the homeless shelter looking for him. He's not there, but she ends up helping serve tea and biscuits.
Kate's mom has a family dinner planned to celebrate Marta's promotion and nothing goes right. Kate's mom tells her she's "wasting her life" and "only a miracle saved her." Marta accuses her of being ashamed of herself because she doesn't care about anything and Kate retorts that she isn't the one who's ashamed of who she is and lets it slip that the woman who lives with her just isn't her flatmate like her parents think, but her girlfriend. Marta is furious at Kate and leaves. Kate also leaves where she has a drink at a bar, then goes to the homeless shelter. It looks like she's about to enter, but ends up walking away and sees Tom come up to her on his bike. On top of being upset about the evening's events, she's also upset with Tom because she hasn't seen him in two days and has been wondering where he's been and that he's "been disappearing for days on end."
After this scene, she starts feeling better, being comforted by Tom and all. She starts doing nice things, like buying a latte for Santa just because it's Monday. She surprises her boss even more when she tells her she's thinking about giving auditioning a break because she's not sure if it's good for her. (She didn't get the Frozen part...I wonder who she was auditioning for, anyway?) Santa commends her, telling her that sounds like a healthy choice and that she hasn't made one of those in a very long time. She also starts singing Christmas songs outside the homeless shelter for donations and is super proud of herself when she receives her first offering. It's not much, but she donates her proceeds to the shelter and continues to sing where she makes more money. She gets the idea to have a Christmas fund-raising benefit on Christmas Eve for the shelter. We even see her right her wrongs, such as apologize to her sister, give a goldfish to a friend when she accidentally killed his super expensive saltwater tropical fish when she absent-mindedly dropped her hairdryer in the fish tank, and gives her married friends who are expecting a baby a big baby basket (and a new model galleon for the husband). Obviously Tom is having a good effect on her and she is wanting to be a better person.
