Yoda does not initially identify himself to Luke and instead tests his patience by presenting himself as a comical backwater individual, deliberately provoking both Luke and R2-D2. Luke is shocked when he finally discovers that this small, eccentric creature is the powerful Jedi Master he was seeking. Finding that Luke has the same anger and recklessness which caused his father's downfall, Yoda is reluctant to teach him the ways of the Force and agrees only at Obi-Wan's behest. Before finishing his training, Luke chooses to leave Dagobah in order to confront Darth Vader and save his friends on Bespin. Yoda and Obi-Wan warn him that he is not ready to face Vader and is being lured into a trap but Luke leaves anyway. When Obi-Wan laments that Luke is their "last hope," Yoda reminds him that "there is another."
