from what I can gather kris and karly didnt say that about noirin I think siavash was banking on noirin not saying anything to the rest of the group cause he said can I trust you before he said it,but when noirin confronted kris and karly they demanded to know who said that to noirin and then It all kicked off,I think marcus had a cheek saying noirin had basically fed siavash to the lions he desereved everything he got in my opinion.hope that answers you're question sort off!
