Wakasa is shocked when Tatsumi leans over the tub and announces it stinks. Tatsumi cleans the tub responsible for the odor and transfers Wakasa to a children's pool. Saying, "Brother, tell me if you're using the pool," Kasumi mistakes Wakasa for Tatsumi and hugs him.
You should've told me 
you were using the pool.
كان عليك إخباري بأنّك ستستخدم حوض الاستحمام‏.‏
Warum sagst du mir nichts vom Plantschbecken.
Debiste decirme antes si te 
ibas a bañar en mi piscina.
Tendrías que haberme avisado 
que te bañarías en mi piscina.
Dis-moi quand tu utilises
la piscine !
Você devia ter avisado
 que ia usar a piscina.
