There's been some great conversation on this one. There has been argument over whats Fhenry meant by bargained for etc...We all say that maybe the others got more from Walt than they had anticipated. What did they want from him? He said that they make him take tests. The Mrs. 'Clue' (whats with that last name)..Perhaps the clue was in her question to michael abotu walt appearing in places that he wasnt supposed to be. Are these others still conducting experiements? Are they still learning? Are they acting on any of this learning?
