Melissa McCall did not pause on her way to see the girl that Derek had brought her. She wouldn't stop not until she knew if her sons would be okay. She could only be thankful that Liam, her boys responsibility weather he wanted him to be or not, was not there. Her son would only worry more than he was now especially with Stiles by his side. Fighting for their life.
She ignored the woman crying over one loss or another when ordinarily she would have at least stopped to give her a kind word or two. No she couldn't stop. Not even the suffering of another person would stop her now.
Her son was in danger along with the people that Melissa had grown to accept and love as being a part of her son. She said a part
She had to know her son was well. She had to.
