As the turbulent 'Suits' Season 4 comes to an end on Wednesday, March 4, fans will see an unexpected new character in the last episode titled 'Not Just a Pretty Face.'

TV Source Magazine claims that Billy Miller, the 'General Hospital' star, will feature in the 'Suits' Season 4 final episode. The veteran actor, who featured in several soap operas and bagged the Daytime Emmy three times, will be portraying the character of Marcus Specter, who is the younger brother of Gabriel Macht's character Harvey Specter.

The TV Source Magazine report further says that the two brothers, who are at opposite poles, are not on the best of terms, as the hugely successful lawyer is often annoyed with the poor life choices of his brother. Nevertheless, as of now the show runners have not provided details regarding the actual intentions of Marcus, or if he will be back for more episodes in the future installments of the hit legal television drama on USA Network.

In the meantime, spoilers for 'Not Just a Pretty Face' reveal that Sean Cahill (Neal McDonough) will be returning to the series in the Season 4 finale. Moreover, he may also necessitate Harvey's help in the future episodes.

The official synopsis for the 'Suits' Season 4 finale reads, "When SEC investigator Sean Cahill fails to link his corrupt boss Eric Woodall and corporate raider Charles Forstman, Harvey must revisit his own uncomfortable past in order to find a way to put them away for good. Mike (Patrick J. Adams) and Rachel (Meghan Markle) confront the fact that, while Rachel is Harvey's associate, Mike is his guy. And Donna (Sarah Rafferty) helps Louis (Rick Hoffman) with an unexpected crisis."

Viewers have already witnessed plenty of drama in 'Suits' Season 4 owing to the activities of the law firm members. During this season, viewers also saw Louis discovering Mike's biggest secret, after he found out that the latter did not really attend Harvard Law School. Therefore, to keep him from disclosing anything, Louis asked Jessica (Gina Torres) to put his name on the wall as well as appoint him as a senior partner of the law firm.
