A manin character will die in the fourth episode title "Pay Off"
Who will die? What do you think?
This is my opinion: Nikita, Michael, Ryan, Alex and Sam/Owen are safe since their names appear in the synopsises for 4x05 and/or 4x06. That leaves Birkhoff, Sonya and Amanda.
Birkhoff appears in this bts picture from 4x06 so I'll assume that he lives.
I don't think that they manage to kill Amanda so quickly (maybe in the series finale) so I don't think it's her either.
Sonya is most likely to die. Maggie Q said "There's a moment at the end of an episode this season where Birkhoff's been through a lot and Nikita comes to try to comfort him." so it is likely that his girlfriend, Sonya dies.
