My thoughts about this situation are that Marvin Redstone, the band manager is stuck between a rock and a hard place. In my views he still is the right person to make the best solution because his main objective is the children and their future. He is contemplating and putting much thought into his decision and is trying to come up with the best outcome to the whole situation, the right and best solution possible for everyone that is involved. The children, the candidates and the chief and the members will all be affected by his decision and to the best of his ability he will not be able to please everyone but will put up a fight doing so.
Each candidate makes a good choice but they all have their pros and cons about the whole situation. Sally Northwind has experience with on the job training but is it proper training? Mike Bluesky has conflict of interest but he has the education. Lucy Bearcat has the experience but she was caught with her hand in the cookie jar.
