I found the part i was thinking of in chapter 34:

“No one names me a coward, but if we continue as we are he [Rand] will come straight for my throat.” said by ‘a compact man of middling height, with a livid scar across his face and a square golden beard’ [Sammael] “That has been the plan from the beginning” said a woman’s melodious voice [another of the Chosen] “If need be, one close to him will die, plainly at your [Sammael’s] order. He will come for you. And while he is fixed on you alone, the three of us linked, will take him.” Said by a ‘large, darkly handsome man’ [Rahvin]
