Why did Victor attack Kayla in the lab?
After Logan leaves Kayla demands Stryker set her sister free, but he refuses. Then Victor confronts Stryker about letting Logan leave and he demands the Adamantium treatment, Stryker says no because he wouldn't survive the treatment. Kayla states that Stryker is lying to them both and she moves like she was about to attack Stryker, then Victor grabs her and threatens to kill her.
I don't understand this. Victor was practically read to kill Stryker himself. Both him and Kayla wanted something from Stryker that he was refusing to give. She could have used her "tactile hypnosis" to make him give them both what they wanted.
Why did Victor grab Kayla and threaten to kill her??
