She rather tilting towards a conclusion of the informant gave him the wrong information, this way no one get hurt, other then that informant that is.
Alex would not be lying as for him, what he said is the truth, while she would also be spared from the shock of strict rule enforcing formal dragon lady used her authority to save her student.
