Invitation Gone Wrong

"Aunt Minerva, why won't you come inside?" Iris asked her. From the corner of her eyes, she saw Monette and Theo were as surprised as her by the actions that Minerva was showing. It was clear that Minerva wasn't happy to be called by Iris. 

Mariano stood alert next to the doorframe, he was thinking of the possible reason why a mere human being called by another human was showing great discomfort. He could not think of any possible reason other than the possibility of Minerva being under hypnosis. 

But from what he understood, it was Calixto who put them under hypnosis, thus, she had no reason to act in such a manner being called by Iris since they were supposed to have the same master. 

And yet here she is, showing unwillingness to head a simple invitation.
