Is it okay to replace "ask" to "say" here?

While you could replace "ask" with "say" you would have to change the whole sentence for it to be grammatically correct. Black Panther says, "I won't ask a second time" and we cannot say "I won't say a second time". It would have to be changed to "I won't say it again" or " I won't say it a second time" in order to continue to be correct.
