Snowpiercer season 2 is going to introduce a new character who will bring further drama and shake up the story even more. Game of Thrones alum Sean Bean is set to play the role of Mr. Wilford, a powerful passenger of the train and ready to cause chaos moving forward.

Previously, TNT dropped the first trailer of Snowpiercer season 2 and it featured the arrival of Bean's Mr. Wilford. The character is going to be the biggest adversary this time around. His presence will cause troubles and problems on the train, especially for the passengers.

Based on the description, Mr. Wilford is "well-dressed, resourceful, and dangerous." His origin when it comes to the train remains unknown, as well as his relationships with other passengers. There are a lot of mysteries about him at the moment, but he'll be a huge thorn to most people on board Snowpiercer.

Viewers will learn more about him as the latest installment of the post-apocalyptic dystopian thriller is coming next week. The premiere, titled The Time of Two Engines," will immediately introduce Mr. Wilford. Each of the characters will try to figure out how to deal with this person.

The premiere synopsis of Snowpiercer season 2 confirmed the official arrival of Mr. Wilford, though it didn't provide further details about him. Perhaps, he's going to show up in an unexpected way, which could lead to tensions between groups within the train.

In addition to Bean's Mr. Wilford, the latest installment will also introduce another significant character. Girl Meets World alum Rowan Blanchard portrays Alexandra Cavill, Melanie's daughter. She was thought to have died seven years ago but emerged in the season 1 finale.

Beyond Mr. Wilford and Alexandra's arrival, Snowpiercer season 2 sees Melanie Cavill (Jennifer Connelley) making a move that can't be undone. She has been one of the essential characters since the series started, and it's interesting to see what would be her move this time around.

Melanie is aware of what's happening on the train. She understands the current environment, including the passengers' feelings. Moreover, she knows some big secrets and she could use these to polarize the situation. However, her actions often cause trouble for her and others.

As for what else is coming, the story will focus on the world beyond the train. The first season follows the passengers finding a way to survive aboard Snowpiercer. This storyline still continues, but there'll be changes considering what transpired in season 1.

Snowpiercer season 2 premieres on Monday, Jan. 25, on TNT.
