When Bruce is left broken and suffering in the Prison Pit, Bane explains that this is where he suffered and where Bruce will fully realize his failure with Gotham, and then be killed.
During his time there, the Doctor and his friend explain that Bane owns the prison, and their only duty is to keep him alive until Bane wants to kill him. However, they seem to turn around, heal his back and start encouraging him to find the will and ability to climb out of the pit.
The question here is, why?
Why would they disobey Bane and help Bruce?
