Prepare for VS. has / have prepared for

(In a movie script)

A: If it reaches peak level...

B: We prepared for this, Doctor.

-----------------------------------------

If we write 'have prepared for this' in place of 'prepared for'? is there a nuance between them you can sense?

Thank you so much as always and have a good day.

Only that the present perfect would tend to suggest more recent preparation.

Thank you so much, so do you consider the past tense in the script wrong?

Oh, I am sorry. I misunderstood the reply. Thank you so much.
