The witty, snappy Donna (Sarah Rafferty) is a Suits fan-favorite for a reason — beyond being hilarious, she's whip-smart and always on top of her job as Harvey's executive assistant. So we were bowled over at the huge twist at the end of Season 2, Episode 4: "Discovery," when (spoiler alert!) Donna discovered that she had misplaced an important document during an old case, opening Harvey up to a fraud lawsuit, and maybe even disbarment.

How could this happen? And what does it mean for Donna's future? Wetpaint Entertainment had a chance to talk to Sarah Rafferty about the twist, and she dropped some hints about what it will mean for Donna, Harvey, and the future of their friendship.

Wetpaint Entertainment: We're still reeling from the end of the last episode. What did you think when you first read the script for the episode?
Sarah Rafferty: I can tell you what my reaction was when Aaron Korsh our writer/creator/producer and David Bartis, one of our producers, told me that was going to happen. They told me before we started the season, over dinner, a couple of weeks before we came up to Toronto [to film], and it was so bizarre. I was like "Wait, what? What? Donna's going to be wrong?" And I started shaking! Like, she's wrong? I don't understand! I thought she was always right. That's her thing! She's always right. And they were like, "She's going to be really wrong about something." So it was really funny, because I was really excited about the juiciness of the plot line, but at the same time almost nervous on Donna's behalf. Like she was my girlfriend that I knew, and I was like, "Oh my god she's in for it, she's going to freak out."

What do you think was going through Donna's head as she discovered that document?
I think two things. There were two very distinctly different things.Right when she first saw it, I think she was thinking "What? This isn't it...This is it? That's my signature? How could this possibly happen?" You know, trying to — that thing that you do. "But, I never saw this. Or did I? When did that happen, how could I do that?" The confusion of "How did this get here?" And then that goes very quickly into "Oh my god, Harvey will get disbarred for this." And then what I imagined on behalf of Donna was "Oh my god, Harvey one of my best friends, who was so excited to get his new office and we left the DA together and he's actually a totally stand up guy, and his dad was really proud of him and now he's going to lose everything and it's going to be my fault." All that stuff.

Harvey and Donna's relationship is founded on trust, and now she's broken that in some ways. Will that impact their relationship, and do you think it can ever fully recover?
That's a great question, about the recovery. I don't know. I think that remains to be seen. It definitely impacts their relationship very intensely, and that's one of the reasons why I was excited about it. Aaron told me even before I read the scripts, he said "It's going to get messy and complicated, really complicated, between them." And you know, that's always fun. It's not something that's easily resolved. It's not resolved in the next 47 minute episode. It's something that's going to continue to impact them going forward.

Will Harvey put himself on the line to protect her?
I can tell you that she expects him to. She really expects Harvey to do that. And to be totally honest, some of that I might not know about yet! But she definitely expects him to, and I imagine that he would. They have such a symbiotic relationship.

We've seen him put himself out there for Mike so many times, so it's definitely something he does for the people he cares about. We'd be a little mad at him if he didn't step up for her, too.
[Laughs] Yeah exactly!
