'Game of Thrones' Season 4 tease: Sam does something with 'catastrophic results'

John Bradley, who plays the character on the HBO hit, tells Zap2it that Sam does an action that could have "catastrophic results."

"There are some times this year where Sam gets kind of unreasonable and selfish and petty, and in the end it turns out that these little bits of insecurity and these kinds of pettiness and jealousy that he has within him can lead to sometimes catastrophic results for him, potentially," Bradley teases. "There are certain decisions he makes this year in regards to Gilly that have the potential to send his whole world crashing down, and they make him really question himself."

He elaborates, "He has another crisis of confidence, for a man who was just on the upward incline as far as self-esteem is concerned. It sends him right back down to ground zero and completely [could] destroy him spiritually all over again just as he was starting to get a bit of a head start on people."

In previous seasons, Sam would call himself a coward, though his actions would prove otherwise. Bradley refers to this as the "romantic irony" of the situation, where the audience knows Sam is actually braver than he thinks he is.

But in Season 4, Bradley says Sam's self-deprecation is "completely justified."

"There's at least one major occasion where he's completely right to hate himself for the first time," Bradley says. "Sam never does anything wrong to anybody and he's usually very, very sensitive to people and gives people room to breathe and tells people what they want to hear. He's a shoulder to cry on for a lot of people. But there are times this season where people are completely justified in really disliking Sam, and in Sam completely justified in disliking himself. There's a lot of self-loathing in Season 4 for Sam, and for the first time it's entirely, entirely justified."

"As soon as you see it, you'll know what it is," Bradley promises of the event in question. "It's little seeds that have grown inside of Sam that he acts upon but shouldn't act upon, and they lead to potentially catastrophic results."

"Game of Thrones" Season 4 premieres on HBO on April 6 at 9 p.m. ET/PT.
