It plays at a moment when Sean and Harveys collusion leads to a victory for both Sean and Mike.
However, those lyrics can pretty much apply to everything else going on in this episode, too.
Actually, lets start with Louis date.

I didnt expect it to take the turn it did and it was my favorite scene of the episode.
This date meansa lotto Louis.
What if Im not good enough?

But Donna pushes that idea out of his head immediately.
It turns out Louis is more than good enough.
During the date, Tara reveals she has a boyfriend who lives in Los Angeles half the year.
Unfortunately, Louis needs a trading database to do so, requiring him to ask Stu for a favor.
Enter Donna, who convinces Stu to lend a hand and makes him reconsider everything about himself.
Im Donna and Im awesome, she says as she walks off.
Stu comes through with the database and Louis discovers whos been feeding Sutter insider information.
Its someone from some consulting bank and…
Honestly, the details arent important.
Anyway, Harvey interrogates him and drives him to Sean.
This is the lead Sean needed to finally put Sutter away.
The good guys won, says Sean, because good is a relative term in this scenario.
NEXT: Things get complicated
You know whoisuncomfortable with everythings that going on?
Mike, whose conscience never knows when to shut up.
She refuses and leaves the meeting pretty angry.
Kevin confronts Mike about talking to Jill, basically saying their friendship is over because he crossed a line.
Unfortunately, it looks like Mike might not be getting out of prison anytime soon.
That night, Sean pays Harvey a visit and tells him that the SEC pulled Mikes deal.
Jessica and Rachel
Rachels case with the Innocence Project is starting to get interesting.
After the meeting, Jessica pursues an execution delay anyway.
However, the judge agrees to give Jessica and Rachel some more time to find the witness.
The father of one of the victims storms into the PSL office and demands to see Rachel.
Hes pissed shes helping the man he thinks killed his daughter.
Thankfully, Jessica and Gretchen have her back in this situation and Jessica comforts her after the traumatizing incident.
