You're Not Welcomed Here

"No one is coming." 

The words reverberated in Sirevius's head repeatedly, he didn't know why, but for some reason, he believed it. He didn't want to believe it, he wanted to believe his father would be able to locate him anywhere in the world, that's what he believed, but for some reason, he couldn't get the thought of Grey being right out of his head. 

If it was before Grey brought him here, he would've never believed his father wouldn't be able to find him, as long as his body wasn't shattered, his father will be able to find him anywhere in the world. The case is different now since Grey was able to drag him out of the Inner Court without his knowledge and consent. Even though he wanted to leave with them, he didn't know when, nor had he agreed to leave, yet he was taken out. Being able to achieve something like that alone means that there's a good chance that Grey truly might be able to hide him from his father's senses.
