The final battle takes place in the Hikariwo theater, where Takuru is trapped in a sightless and soundless prison in his own mind.  He'll need Onoe's help to break free, but after what he knows about her, can he bring himself to ask for it?
You just want him to solve the case, right?
فأنتِ تريدينه لحلّ القضيّة فحسب، صحيح؟
Ist doch in Ordnung,
wenn er die Mordfälle löst.
¿No te basta
con que solucione los casos?
¿No te basta con solucionar los casos?
Tout ce que tu veux,
c’est qu’il résolve ces crimes, non ?
A te basta che risolva il caso, no?
Você só quer que ele mesmo
 resolva o caso, não é?
