'She is already this dangerous.'
Seeing her performance in the battle, Alfin's desire to kill her heightened to a certain extent. While, After his talk with Yakub, his intention to kill this man was lowered.
Which put him in a tight place.
Because doing either of them would be problematic and he had promised Tarkov about it as well. Going back on his words would in turn cause his companions to lower their trust in him, it doesn't matter how sensible a choice he was making.
"She is strong, who is she?" Alfin asked while being aware of the answer. As he wished to hear about Thalia from Yakub's mouth.
"She is someone whose sister you killed." And it would seem that Yakub had no intention to hide the matter from Alfin.
They were already far enough and Thalia's senses were still not on the level of Alfin. So it was easy for both of them to whisper.
Making Alfin who just learned the reason why she was after him, tighten his body all of a sudden.
'A sister?...'
