Louis comes up to Donna's desk to apologize for his behavior at Harvey's fake trial and he seems to mean it. "I just don't have the words," he says sincerely. "Find them," Donna orders after a long spell of not even looking at him. Looking at him doesn't help though, because all he comes up with is "I'm sorry. I'm so, so sorry." That seems to satisfy Donna, but Louis isn't done; he hands her front-row season passes to Lincoln Center. "Do I have to go with you?" she asks. "Hell, no!" he says happily and she accepts them gratefully. Louis is clearly experiencing the euphoria that comes after getting through something you were deeply dreading, and celebrates, "God, could this day get any better?" Donna wonders what else happened today, "You look like you have eighty teeth." As opposed to his normal sixty. She also notices that he's wearing Brioni and suddenly says, "Oh, shit" as she jumps up from her desk. Looks like she got back just in time.
She finds Jessica in the hallway and quickly accepts her welcome back (and declines to apologize or ask for a raise) before breaking the news that Hardman secretly made Louis senior partner, which she knows because Norma told her four years ago that Louis bought a suit for this day and he's wearing it now. Jessica realizes this means Hardman bought himself another vote and asks how the suit looked. "Dated," Donna says after a thoughtful pause. If she ever gets fired again, it had better be for shooting Jessica in the face.
Mike and Harvey are walking through the hallway, Harvey pissed at his client for throwing around unfounded accusations, while Mike assures Harvey there are ways to pass tests without actually passing them. And as someone who has passed hundreds of them for other people, he would know. Just as they're going by Rachel's office, she steps out in front of them -- with Mike's grandmother at her side. Meeting her for the first time, Harvey turns on the full Eddie Haskell, at least until Grammy mentions that Mike tells her Harvey's quite the hard-ass. "Hard-ass isn't really the word he uses," Grammy self-corrects. "I see lip runs in the family," Harvey says as though it's not just that the writing doesn't provide much variation between character voices on this show sometimes. After Harvey marches off, Grammy explains to Mike that she ran into Rachel downstairs (although she doesn't explain how they knew each other) and Grammy shows off the sack lunch she packed for them. "Might as well have brought it to me in a Star Wars lunchbox," Mike says gratefully. Grammy guilt-trips that he hasn't seen her in two months and wants to meet some of his co-workers. After she embarrasses Mike in front of Rachel and he drags her off, she agrees, "Fine, just let me meet that Harold clown and I'll go." Mike will probably want to be sure he brings her to Harold's desk from the other side of the monitor.
