|S2 Episode 11 - I'm a Confused Chicken|
The club's movie screening gets cancelled because Rika is sick from working to hard to finish it on time. Yozora said that it wouldn't be right to screen it without all the club members present. After Rika recovers, she shows the movie to the club.
That red-haired girl, Yusa Aoi, starts becoming relevant again now. Ever since learning that Sena joined the Neighbour's Club, she's gotten curious about what that club does and has started spying on them. Finally she gets mad and barges in to complain about how they're always just playing around in the club room.
Yusa is part of the student council, which is why she thinks she has the authority to complain about this club's activities. Once Yozora learns that Yusa considers herself Sena's rival (while Sena hardly even knows she exists), Yozora starts telling her about the club the same way she used to recruit new club members in the first season.
The Neighbors Club is officially recognized by the school, and we abide by its stated aims.
In compliance with God's instructions, we become neighbors with our fellow students, deepen that friendship, and, as occasion may require, sincerely work hard together.
In other words, what appears to be mere playing around is in fact perfectly legitimate club business!
Yusa keeps trying to bring up ways that this club is breaking the rules, but Yozora keeps shutting her down by explaining how it's not actually against the rules. Then she figures out that Maria isn't a real staff member, and that makes their club invalid because they don't have a proper club advisor. Kotaka calls Kate and she confirms that Maria is just her assistant and she just dresses up in a sister outfit for fun. So then Sena makes a call to her dad and somehow easily makes it so that Maria became an official sister. She then goes and shuts down Yusa even more than Yozora did, making her cry and run out of the room. Sena doesn't tolerate anyone getting in the way of her gaming...
Oh, and then as she resumes playing her game, she casually brings up that she wants to marry Kotaka after all... The mood changed really abruptly. Kotaka tries to pretend he didn't hear Sena and then makes an excuse to leave rather than answering her.
