Suits creator Aaron Korsh is guessing you had the same thought he did after last week's episode.

"After we finished shooting it, I was like, 'Can this just be the summer finale?'" Korsh tells TVGuide.com. "It really could've ended right there and it would've made sense."

Fall TV: Hot scoop on returning fall shows

Despite saving the firm from the SEC last week (watch it here

), Louis (Rick Hoffman) couldn't get back into Jessica's (Gina Torres) good graces for his dirty deal with Forstman (Eric Roberts). Before she could fire him as threatened, Louis preemptively left a resignation letter on Harvey's (Gabriel Macht) desk, asking them to take care of Pearson Specter, aka his "home." "The writers pitched me Louis resigning and hearing the letter read in his voice," Korsh says. "It was so moving to me that I thought it was a great thing to aspire to get to this year. I loved it."Like Mike (Patrick J. Adams) before him, Louis' exit from the firm doesn't mean he's no longer around on the show. In fact, Louis casts a larger shadow on Wednesday'smidseason finale (9/8c, USA) in his absence than he did working there. The episode kicks off with Louis asking Harvey for a favor as he tries to find a new job. Some want to lend a hand more than others (ahem, Jessica), but "pretty much everyone is going to rally aroundLouis to try to help him with varying degrees of success," Korsh says."Louis is in a bad way," he continues. "There are ramifications of his resignation on everyone at the firm. Louis is very deeply connected to everyone and all of them care about him. Mike, for example — Louis brought him back to the firm. In addition, Louis forgave Mike last year when he told him that he changed his grade on his transcript, so Mike really wants to help Louis."

But Mike's willingness to pay back Louis could bite him in the ass. He goes out of his way to help Louis, leading to a big move that triggers major consequences — and an enraged Harvey, as seen in the promo. Might Mike feel so indebted to Louis that he comes clean about his (lack of) Harvard credentials — especially now that Louis doesn't work at Pearson Specter anymore? "Mike does something ... that sounds good," Korsh teases. "But it takes a turn that he doesn't see coming. He is also feeling vulnerable right now and that he has something to prove because he knows Jessica doesn't want him back and she was forced to take him back because of [his secret]."Mike's return to the firm after his disastrous foray into investment banking was hardly Earth-shattering and probably most unpredictable in how long it took (seven episodes!). Donna (Sarah Rafferty), lest we forget, also returned after getting fired, so the hot money is on Louis to eventually (inevitably?) come back."Sometimes I hear people say that things are predictable. I would say that I would imagine most people, when Mike turned down the job in [Season 3, Episode] 15, said, 'I saw that coming,' which means they saw it coming that he'd do it in 16," Korsh says. "Even though they think he's definitely going to come back, the hope is they'll question, 'Well, I was so sure he was never gonna leave, can I be sure that he's going to come back?' ... Even if someone can predict something that ultimately will happen, the question is, 'Can you predict when it's going to happen?' and 'Can you predict how it's going to happen?' Hopefully you can't predict either of those things and you'll be compelled along the way."

Fall TV: Must-see new shows

Korsh is also hoping fans will be compelled to wait for the remaining six episodes of the season after Wednesday's final minutes, which include "lots of fireworks." "Last year, when we ended with Mike leaving the firm, I didn't know if people would feel that was a cliff-hanger or not," he says. "It was really a resolution, but it wasn't a total cliff-hanger. This one, I think it's more of a cliff-hanger. You're definitely going to be wondering, 'What's going to happen?'"Suits' midseason finale airs Wednesday at 9/8c on USA.
