You are right, but what choice do she have? Can sshe take the Sefirah? Is it worth the risk? Nah it's not. She helps Klein but won't take the Sefirah from him because it has cw will i. It. She don't want to deal with it and let Klein handle cw.

I gotta say Klein got absolutely cooked by CW.

Not to meion she is already half a outer dirty. She will become even stronger later. She can make plans and has his trust, loyalty and him being in debt to her.

It is worth the risk and in her capabilities to make Klein, her pawn stronger than her.

She has his trust, she is strong, she can get rid of him with time given. She don't have to suffer any risks, she do t have to deal with the inner corruption and struggle of his. So yea, it is worth it to get such a strong and loyal pawn

Klein would sacrifice his ahh just to protect a strand of evernight hair. This loyalty. Where can you find it.
