Shimamura just happens to run into Adachi's mom at the gym and they have an awkward encounter. Later on, Shimamura invites Adachi to karaoke with Hino and Nagafuji.
I don't... know Ada... your daughter very well,
Ich weiß sonst zwar nichts über Ada…,
über Ihre Tochter,
No conozco muy bien a Ada, su hija…
No conozco a Ada… a su hija,
Je ne connais pas très bien Ada…
euh, votre fille,
Io non...conosco Ada...sua figlia benissimo,
Eu não conheço muito
bem a sua filha,
Я мало знаю об Ада… 
о вашей дочери,
