When Sacagawea arrived to serve as interpreter, she found the band was led by her older brother, Cameahwait, who had become chief on their father's death. Deeply moved by this reunion, Sacagawea might have taken advantage of such an astounding coincidence to return to her people, but instead she helped the explorers secure the horses they needed and journeyed on with them and her husband to the Pacific. "Clark saw Sacajawea, who was with her husband 100 yards ahead, began to dance and show every mark of the most extravagant joy, turning round him and pointing to several Indians, whom he now saw advancing on horseback, sucking her fingers to indicate that they were of her native tribe."
