[Dustin's viewpoint]
Dustin didn't know what had hit him, but he was too angry at Ty to be afraid. Sure, he and Ty never got along very well, and he knew Ty didn't like him or his parents, but he'd never dreamed that Ty would hurt June. That was really beyond the pale. It made what Ty had done to him seem insignificant by comparison. In his anger, he hadn't really been listening closely to the conversation. Listening was never really his strong suit anyhow, which was part of why he didn't get good grades in school, and tended to get in trouble frequently. Now, however, he somehow was frozen in place, unable to move a muscle, other than to move his eyes. While he tried to think of a way out of this predicament, and ways to punish Ty, it was hard to avoid listening to the walking dead twerp talking to Mark.
Mark would never put up with any shit from Ty, or anyone. Especially anyone threatening him or his family. Yet rather than protecting his wife or Dustin, or beating the crap out of Ty, he was just sitting there pleading with Ty not to hurt them! What the fuck was going on? Mark was just listening to Ty's namby-pamby bullshit about not wanting to hurt them. Well, Dustin would hurt Ty plenty for this, as soon as he worked himself free. He didn't know what was binding him, but his asshole of a stepbrother was obviously behind it somehow, just as he had to be behind regressing Dustin's body.
Attacking their mother! What an unspeakable little monster! Mark still did nothing as Ty got up and went to the kitchen. Dustin screamed at the top of his lungs for Mark to fucking do something, as the only real family member who had the ability to move, but not even a whisper escaped from his mouth. "Ty must have somehow turned Mark into a pussy," Dustin thought. "Even more reason to kill the little bastard at the first opportunity."
He looked to June, who was apparently just as frozen as he was. They made eye contact, but he didn't get any sense of her emotions before she looked away. She didn't appear to be in physical pain, though. Maybe Ty had plans for her. Maybe he'd somehow break her will, as he'd obviously done to Mark. "He'll never break me!" Duustin swore. As he continued thinking about the situation, his anger just rose and rose.
Ty came back into the room with water, sat down, and turned to June. If angry looks could kill, Dustin would have killed Ty many times over. All of his imagination was focused on things to do to Ty, and he never paused to imagine what more Ty might do to him.
