Rio learns that his mother's ears have turned into pot stickers because his older brother Yuu was kidnapped, and Rio feels responsible for what happened. When Rio nearly falls off a cliff while searching for Yuu, Ramune throws himself in harm's way to protect him and ends up badly injured. In order to save Ramune, Rio uses the Pearl of Night Voices he received from Ramune to treat his mother, desperately calling out to his mother, who can't hear his voice.
In other words, the two 
of you should talk a lot.
.أي أنّ عليكما أن تتحدّثا كثيرًا
Anders ausgedrückt sollt ihr zwei
ganz viel miteinander quatschen.
Así que tendrán que conversar mucho.
ll vous suffit donc
de parler de tout et de rien !
In altre parole, dovrete parlare un bel po'.
Ou seja, vocês só precisam
conversar um montão.
В общем, вам двоим нужно
много разговаривать друг с другом.
