This episode is very special and well written. It was classic to present some emotional scenes as the show's standard. Moreover, all casts looked great in the ancient medical uniforms (during the delusional flash back scenes of the old man). The storyline is very nice to portray a story of an old doctor who had developed the ER system came back and finally rested in peace after he had seen some good medical improvement as he wished. It began with a mystery old guy wondered into ER. While, staffs are trying to get his identity, this old guy helped Dr. Brenner to correctly diagnose a cancer case as a TB patient instead (even though he was losing track of time). Finally, Dr. Morris noticed him as an ER medical legend and Dr. Morgenstern returned to ER for him as well. Dr. Morgenstern asked to move his former mentor into the trauma room for some privacy while they took off the ventilator. Fortunately, the old doctor got to see some medical development at his final.
For some character development, Sam got to see her out off touch sister and tried to deal with their mother issue. Furthermore, Dr. Morris got some silly police threats for seeing Officer Diaz, while Dr. Rasgotra's future job is still ambiguous.
