This episode was phenomenal.

Originally why does Mr.Milchick want Mark to return to Lumon? Seriously what did he originally fire Dylan and Irving. There must be something VERY special about Mark that we don’t know about. What do you guys think it is? Why does Irving lie that he was watching a TV to Mr.Milchick when he is actually printing the hallway from Lumon where Ms.Casey (Gemma) went towards for testing.? So many unanswered questions.
