...disappear. The family hadn't treated him very well, and while Dustin was kind of fun for Ty to mess with considering they were of similar age and of at least a similar type of standing in the family. Well he was significantly lower in the pecking order, but they were both in the role of a son or brother. The "parents" were really enraging to Ty though and he just wanted them gone.
June walked into the room to see if Ty was using too much soap or wasting anything right as Ty had wished for her and Mark to disappear. To Ty he noticed June walking in, and then a void appeared where there was once a body holding up a dress and underwear. Air rushed in creating a breeze as gravity pulled the empty clothing onto the ground. Mark who was currently driving somewhere managed to cause a car accident with his own disappearance. For the world and universe it just looked like the couple was erased, but luckily or unluckily for the couple Ty used the world disappear. He held enough malice to want them gone from his life forever, but not enough to kill them in anyway. So his unlimited power just tore a hole in the universe and pushed them out. No one can really imagine what it's like outside all of existence, and for sure at this point Ty didn't know either... However it probably isn't very friendly to life.
Of more importance to the rest of us Ty started to feel the universe react to him shoving two people outside of it. He got the feeling that the universe wanted a continuity that his powers messed with. It didn't fix itself immediately, but it was slowly making the universe make sense that Mark and June didn't exist. Looking at what was once June's clothes on the ground they started to fade... or teleport is closer to the right word. June after all had purchased those clothes at a store, and now they were going to whoever would buy them if June didn't. Failing being bought they'd either still be on the shelves, sent to some outlet, or destroyed. Mark's traffic accident was also solved as you can't crash a car without being the one who bought the car... or got a drivers license... or ever existed... Ty could feel the Universe start to try to pull him somewhere else. Probably the Foster Family who was next on the list, but Ty remembered one detail that would be rubbed out of the universe that he didn't quite want to remove. Ty started walking but then remembered his powers... and started being annoyed with himself for not making the dishes done already.
Dustin in his room having experienced the universe collapsing in on him and forcing it's changes on himself physically, mentally, and spiritually. Retroactively a runt of the litter who was loved by his parents, and spoiled rotten in comparison to his adopted younger brother. Now however the universe was collapsing in on him again, but this time the universe didn't care about changing his mind in the slightest. What did the universe care about what things that didn't exist think about? Ty however warped in, and sensing what was going on with his powers was holding the universe at bay. Ty's mind was already impervious to the universe's retroactive alterations, but as the house started warping as a different family had bought the house instead Ty was able to preserve Dustin a little.
"What's going on Ty?!?" Asked a scared Dustin who had started to feel himself fade into the Universe.
"...Kinda made your parents disappear for being jerks, and now the universe wants to sweep their existence under the rug in a matter of speaking." Ty explained as a plan formed in his head as Dustin's roomed started warping into the room of a teen girl... then the teen girl materialized in there as she was getting dressed, and Ty then forced her out of her room dressed.
"Well can you bring them back or something?!?" Dustin asked desperate to survive this ordeal, and his mind not comprehending what was going on. Ty probably could bring them back, but wasn't really feeling it right now. He however had a plan.
"Mark or June?" Ty asked
"Wha-?"
"Mark or June!" Ty asserted. Dustin could tell now that Ty was making him make a decision, but what on earth was he going to do depending on who he chose? "Taking to long..." Ty said impatiently as he stopped stopping the universe from blanking Dustin from the universe. Dustin feeling himself relatively quickly vanishing made his decision.
