As a french, i can tell you :

In French, Hythlodaeus clearly say that Emet-Selch should have recognized our soul since "the affection" he had for him/her (our predecessor).
And more, when Emet-Selch see an Amaurotine in our place, he don't just say "No, it can't be" like in english (meaning he could just be surprised to see any amaurotine), but "How is it possible ? You ? Here ?" so he specifically recognized him/her in us.
