So what did Gabrielle Giffords say to Jared Loughner in Spanish?

The WSJ re the 2007 meeting:

Mr. Loughner said he asked the lawmaker, "How do you know words mean anything?" recalled Mr. Montanaro. He said Mr. Loughner was "aggravated" when Ms. Giffords, after pausing for a couple of seconds, "responded to him in Spanish and moved on with the meeting."

So what got his goat? Did she say something derogatory about deconstructionism, Sarah Palin's secret grammatical strategy for world domination? Or was it more like, "Hey man, get a translator"?
