Kalinda felt, more then saw, the portal close, and she screamed. She screamed in frustration, in rage, and in grief. But she didn't let herself cry, as she began the process of tying Frost up, even though she wanted to kill him. She went through the motions almost mechanically, without any feeling, even though her fingers felt numb. She swallowed and stepped back, and then she turned, to where Zack was trying to save Michael. 

She walked over, kneeling down, unable to think of anything to do. "Please, Michael" She whispered, her throat raw, her voice thick with emotion, trusting the others to watch Frost.
