Kalinda cursed when she heard the voice of Arnold, and flinched away in time to not be pushed back. Beyond Griffin and Zack, she didnt much like their third personality, and without much thought, she chased after them. "Hey! Arnold! what the hell do you think you are doing?" Why, why, why did he have to return? She didn't know Arnold, and had no idea what to expect. 

"Damn it, Griffin! Zack! I know you can hear me!" Although she didn't know that, as chances were, if Arnold was in control, then the two were pushed back. Or so she thought from the time she'd interacted with Arnold.
