She said Annabeth would cause Percy problems in the future. She also said Annabeth would have "a hard task ahead of her when you (possibly meaning Percy or Percy and Annabeth) arrive in Rome." Also, when Percy says she is the person he most wants watching his back, Hera makes a statement suggesting otherwise. If Percy cant trust her to watch his back for whatever reason, why would Hera even want her to be in the seven. There are a lot of hidden meanings in this conversation so it is hard to get a straight answer. I think Annabeth does have an important choice ahead of her and so does Percy (as Hera and Mars talk about a choice involving Percy's flaw), but we dont know exactly what this choice is
