If the new season of House of Cards had a subtitle, it would be War of the Underwoods - but will Francis (Kevin Spacey) or Claire (Robin Wright) come out on top?
Michael Kelly - who plays Frank's loyal aide Doug Stamper - told Digital Spy which side he's on in the vicious feud.
Kelly also reveals whether we'll see "Stamper reborn" after the dramatic events of the season 3 finale - and how he's feeling about the loss of original House of Cards showrunner Beau Willimon.
Season four of the Emmy-winning series will see Neve Campbell, Joel Kinnaman and Ellen Burstyn join the cast.
House of Cards has already been picked up for a fifth season, with series writers Melissa James Gibson and Frank Pugliese replacing Willimon as showrunner.
House of Cards season 4 is available to stream exclusively on Netflix from Friday, March 4.
