Outside Hardman's office, Harvey runs into a smirking Louis, who accuses him of kissing ass before entering Hardman's office himself to do some ass-kissing of his own. Hardman explains the situation to Louis: his victory isn't complete unless the firm is united, and that means dealing with Jessica's "pit bull." Louis balks at the idea of firing Harvey outright (which Hardman says isn't an option with Harvey being a senior partner anyway), but when Hardman informs Louis that the target Harvey just pasted on Hardman's back extends to Louis too, Louis asks for his orders. Notice how Hardman just assumed Louis voted for him, without any confirmation from Louis? Notice also how there's a Twitter poll on the screen inviting us viewers to guess whom Louis voted for? A seasoned television analyst like myself picks up on these subtle clues.
Louis finds Mike in the bathroom and hands him some cases -- and his new marching orders. He's not Harvey's any more, he belongs to Louis. "I don't belong to anyone," Mike says angrily. "Well then quit," Louis snaps back. "Your days are numbered here anyway. You don't get this shit done, I'm going to fire you myself." So at least some things haven't changed.
Louis comes and finds Harvey and Donna packing up Harvey's office, and not only does his very appearance drive Donna from the room, Louis hands Harvey a crappy little ERISA case to work on and informs him that he can't pawn it off on Mike, since Mike's work is going to be less "Harvey-centric." I think everyone's in that loop now.
But of course Harvey goes right down to the bullpen to give the ERISA case to Mike. He seems to think nothing has changed, but Mike's not playing, for more reasons than one, only one of which Harvey even knows about. But soon Mike is sassing Harvey pretty hard and loud about his delusional no-lose world having come crashing down. Without even bothering to ask what's up, Harvey orders, "Go home. Now." Mike goes. Now. And at home, Mike sheds his jacket and tie, digs out his new weed and his old pipe, and sparks right up.
The next morning, Mike wakes up on his couch, in his clothes, with an empty chip bag on his chest and a knock at his door. It's Rachel, there to pick him up for the funeral, and he's waaaay late. She offers to help him put himself together, and discovers the bag of weed on his coffee table. Mike tells her to lighten up, saying it was one night, but agrees to flush the rest. Or at least pretend to.
