Sir Keith, your weakness is 
that you have no human allies.
.كيث-ساما، نقطة ضعفك هي أنّك لا تملك حلفاء من البشر
Lord Keith, woran es Euch mangelt,
sind menschliche Verbündete.
Keith, tu punto débil es que
no tienes aliados humanos.
Keith, tu punto débil es que
no tienes aliados humanos.
Keith, vous n’avez aucun allié humain,
et c’est là votre plus grande faiblesse.
Keith, la tua debolezza più grande 
è non avere alleati umani.
Sir Keith, sua fraqueza é
não ter aliados humanos.
Господин Кит,
