There was certainly a lot of "Discovery" taking place on Suits this week, some of which threatened to besmirch the good name of the firm, its clients and the associates.

With Harvey was among those hit the hardest, Donna may pay the price for a mistake made four years ago.

One things is certain: Travis Tanner knows how to come in and upset an already tipping apple cart. And this isn't the first time he's done it.

Unfortunately for Harvey, that time he had the upper hand in the ethics department. This time, Harvey's tactics might actually catch up to him, even if these particular accusations are false. Perception is everything, and if Tanner has his way, Harvey will be perceived as a fraud.

Not to mention the fact that Donna will have to come forward with the document that proves that Harvey had the opportunity and possession of the report often referred to as "the smoking gun" in the Coastal Motors case.

When Donna discovered that it not only existed, but she had signed off on it, she was clearly devastated.

I've surmised that this season was tailor made to challenge the relationships of these characters to one another and in in relation to the firm as a whole, and it's starting to add up to just that.

Jessica and Harvey should have known better than to put off telling Hardman what was about to come at them, especially since it involved a potential lawsuit.

He may be their mutual arch nemesis, but when he has time and again referenced his apparent desire to keep the firm on the up and up, they should have know Hardman would blow a gasket.

But, when you really think about it, who was truly responsible for that timeline significantly shrinking?

That's right: Harvey.

Louis continues to be a loose cannon at this firm, willing to flip to whatever side will most benefit him. He's not below ratting out his enemies in the heat of the moment, which is exactly what happened here. If Harvey had just listened to what Louis was proposing and taken him seriously, he likely would have not only gained an ally in the fight, but spared himself Hardman's wrath.

I am intrigued by the possibility of Jessica, Harvey and Daniel all working together to deflect this lawsuit. Are they capable? Certainly. Is it feasible? With their checkered past, it's hard to say. For the health and future of the firm it's completely necessary that it does.

I'm really worried about Donna going forward. She's my girl. It's going to be terribly rough to suffer through her possible persecution in the coming week.

Another one of my girls, Rachel, had quite the encounter with Harold, the awkward associate who embarrasses me just by being on the screen. He's so socially inept and awkward that you can't help but love him. But what on earth was that all about in the law library? It was like he was just now realizing that Rachel was a looker.

Come on. Seriously? Like that's not a given from first sight?

Sadly, for Harold and his stapler, their relationship will go no further than her research for his cases. Quite frankly, I'm okay with that. Props to him for effort, though.

Some other highlights from the episode:

• Team Litt/Ross. Enough said.
• Harold walking in on Donna and Mike. Best cover up plan ever, Donna.
• Louis deciding to leave his infamous recorder in Harvey's office.
• Rachel having a drawer dedicated to staplers. In my opinion, she should be using the red one. It's cute.

What do you think the strain of Donna's discovery will put on the firm and Harvey's lawsuit? Are both their careers about to be irreversibly besmirched?
