Fans of "Suits" are always looking forward to the dynamics between Harvey Specter and Mike Ross, and Gabriel Macht teased spoilers for season 4 as he said that the two main characters will continue to teach each other.

"We had a good time. Mike needed to spread his wings and as much as Harvey didn't want that to happen, he doesn't control Mike, so he had to allow that. I think they continue to teach each other lessons along the way - and rib each other as well, while they're at it," he told Digital Spy.

Gabriel Macht teased "Suits" season 4 spoilers as he said that Harvey will start to doubt whether Mike is worthy to be called his equal.

"Mike really wants Harvey's help in the beginning and Harvey makes a real error of judgment in that he doesn't trust Mike and that creates a lot of conflict between the two, as you'll see as the episodes continue," he said.

The Hollywood Reporter dished "Suits" season 4 spoilers when it claimed that Stephen Macht will return to the show to work again with his son.

"Stephen will be reprising his role as Harvard Law professor Gerard, notorious for his high standards and rigid ways, in two of the final six episodes of the season when Suits returns in early 2015," the THR's "Suits" season 4 spoilers said.

Previously, Variety has reported that "Suits" will be renewed for season 5 for 16 episodes.

USA Network president Chris McCumber said in a statement: "'Suits' continues to fire on all cylinders, delivering provocative storytelling and complex characters that viewers can't get enough of."

Prodded for more "Suits" season 4 spoilers, Gabriel Macht said, " I think the game-changer is on a personal level [this season] - there's some shifts going on in the office and there's some real challenges that the character's have with each other and with their commitment to each other. But yeah, I guess there is a bit of a change that's gonna be like, 'Holy s**t, how are they going to work this out?'"
