Say What?

In the beginning of Parshat Vayigash, Joseph reveals himself to his brothers.  Upon revealing himself, Joseph gives a speech, mostly about the prospect of his father and brothers joining him in Egypt.  After Joseph's speech, the Torah says "and his brothers spoke with him."  However, the Torah does not tell us what Joseph's brothers said.  If the content of the brothers' comments is not important to record in the Torah, what is the significance of the fact that they spoke to him?

One possibility is that this verse is a reference to a verse in the beginning of Parshat Vayigash.  When Joseph tells his brothers about his dreams of family domination, the brothers get so mad that "they were not able to speak to him peacefully."  Thus, the verse in Parshat Vayigash may be coming to tell us that now, for the first time since Joseph's dreams, the brothers were able to speak to him.  It is a closing paranthesis, as it were, of a period of strife between the brothers.
