You're a valuable hostage,
so I can't kill you...
...أنت رهينة قيمة، لذا لا أستطيع قتلك
Du bist eine wertvolle Geisel,
also kann ich dich nicht töten,
No puedo matarte porque eres una rehén,
No puedo matarte porque eres una rehén,
Non posso ucciderti, 
sei un ostaggio troppo prezioso.
É uma refém valiosa,
não posso matar você,
Я не могу убить тебя, заложницу…
