The greatest effect of Alma's words is upon Zeezrom. While Mormon generously attributes the change in Zeezrom to the ability of Alma and Amulek to see through his designs, it is most probable that we are seeing the Spirit on Zeezrom. His plan was not so cleverly cloaked that it was that difficult to uncover. These were rather standard points of difference between the Nephite religion and the order of the Nehors. Something was being awakened in Zeezrom that he had perhaps not known before. The result of Zeezrom's confrontation so far was that the Spirit has begun to touch him, and now he relinquishes the role of the questioner-to-entrap, and becomes a questioner-to-learn.
Zeezrom's question picks up where Amulek left off. This is precisely a point where Zeezrom's learning has given him different answers than he has just heard from Amulek, and he is now open to learning more.
