Legolas walked over to join the man and hobbits after retrieving his packs from Lightening. He had a dream two weeks ago that Estel was in danger. It was much like the one he had 5000 years ago about Arameius. Since he did not wish to use his magic where his love was concerned, he had traveled to Lothlorien to consult the Lady Galadriel. As soon as he found out the man was headed for Bree to meet Gandalf and escort the Ring Bearer to Rivendell, he knew that was where the danger laid.
