''WeekendAtHisaos's'' is a Katawa Shoujo fanfiction written by themocaw. Set a few months after Shizune's Good Ending. It tells that story of Shizune and Hisao being reunited in Hisao's hometown for a weekend so that Hisao can introduce her to his parents.This story has examples of:
Brutal Honesty: Takumi to Hisao, regarding why everyone drifted away from him during his time in the hospital. He's somewhat more sympathetic to Hisao than the below quote implies, but this clearly takes Hisao off guard.
Takumi: You were an asshole back then.
Call Back:The proposal scene features a piece of veal cutlet bread like the one for which Hisao and Shizune played Rock Paper Scissors; Shizune immediately suggests tearing it in half, though.
Chekhov's Skill: Shizune points out early on that she can talk, but she sounds so awkward she has stopped doing it for fear of embarrassing herself. During the proposal scene, her hands start shaking so badly she can't sign, and after accepting the ring, says "I love you Hisao", which he considers, in spite of its delivery, "the most beautiful thing (he's) ever heard".
Crazy-Prepared: It is revealed in this fic that Shizune was taking birth control pills for a month prior to the sex scene at her house in Act 3 of her route.
Dare to Be Badass: Misha gives Hisao one of these speeches near the end of her phone call to Hisao to convince him to take Shizune to his friends' party and face his remaining demons from that fateful day in the snow.
I Need to Go Iron My Dog: Hisao's friends method of excusing themselves from their meeting with him at the food court. The fact that they had come there for lunch makes it all the more unconvincing to Hisao.
Innocently Insensitive: While Hisao was in the hospital, Mai proposed going to Tokyo Disneyland once he got out. Since his heart condition precluded going on any of the rides, this only served to further upset him.
Mile-High Club: Hisao and Shizune "join the club" on the way back from Lilly's wedding, but Hisao decides it's overrated, especially when the stewardess catches them.
Out-of-Character Moment: Some found Hisao getting upset over Shizune calling him a "coward" to be this, arguing that he should be used to it by now.
Parents as People: Hisao sees his parents as people who worked too often to spend much time with him, but notes that they did so in order to allow him to grow up in a nice house, which they would give up to cure him. Shizune is frustrated with her father's persistent attempts to get her to speak, but appreciates his not treating her any differently from Hideaki and sees him as wanting her to succeed.
Second Love: Takumi for Iwanako. The two eventually break up and get married to other people
Hisao's reminiscing on what his former classmates are up to are essentially one big shout out to the fandom's reaction to the initial pan shot of 3-3's room.
In particular, "that foreign kid" Lezard is studying biochemistry, Suzumiya is working on becoming a film director, and Taro has worked at a toy factory, a brewery and even been a fisherman for a while.
When Hisao is discussing what his former classmates at Yamaku are doing now, he mentions that Hanako is working as a a freelance writer.
Tactful Translation: Hisao takes up this role in Misha's place, doing a notably more graceful job
Shizune: (regarding the Student Council at Hisao's old school) [Amateurs.]
Hisao: [Be nice.]
Shizune: [I am being nice. Still, you, Misha, and I did ten times more work than that, with only the three of us.]
Ryoko: "What's she saying, Hisao?"
Hisao:"Oh. Um. Shizune's saying that our student council was much smaller. It was a lot of hard work."
They Do: Hisao proposes to Shizune before she goes back to school. They get married in the Distant Finale.
We Used to Be Friends: Hisao's reunion with his old friends is awkward at first, especially when they deal with the way he acted in the hospital, but it ends well and they get invited to his wedding.
What the Hell, Hero?: Shizune calls Hisao out for being a "coward" for being hesitant to see Iwanako again, and Misha calls him out for upsetting Shizune.
Yamato Nadeshiko: Shizune's mother, according to her. Her "touch of iron" comes into play when she argues with her husband for the only time Shizune can remember, over his hiring tutors to get Shizune to speak.
