There's trouble at the beach.  The four swim club members are forced to revisit their motivation to swim.  After Rei asks Makoto about his odd behavior during the training camp, Makoto tells them about his past.
Because Rei is for refriger-"rei"-tor!
Weil das Zeichen für Rei...
 auch in Kühlschrank vorkommt!
¡La "r" de Rei-chan es 
la "r" de refrigerador!
Porque "Rei-chan" tiene 
la "R" de "refrigerador"...
Parce que c’est 
un rei-frigérateur !
"Frigorifero" = Reizouko
Porque "Rei" lembra "Rei-frigerador".
Потому что Рэй есть в слове
«рефрижерэйтор».
