Milo shrunk back, and he did look at Xander, and he did listen to him, and somewhere deep inside even believed Xander was probably right, but it didn't make it easy to hear. Being told he couldn't trust his mom was, maybe, was one of the hardest things he had ever been told. And being told he'd be in the way, and make it harder on her, if he was with her, too. Clenching his jaw was the only thing that stopped him from screaming, he wanted to scream, he wanted to be sick, he wanted to run, or something, but the part of him that did agree with Xander said stopped him, even though the awareness he wasn't completely wrong made him want to scream even louder.
"Why are you calling my Stitch?" He forced out the words, because it was the only part of anything Xander had said he felt like he could respond to without collapsing in on himself, "The whole point of that movie is that if you're a family, nobody gets left behind. The whole point is that Lilo's sister, even though she wasn't perfect, did her best, and Lilo was better with her than she would've been away from her, so it doesn't even make sense." He took a deep, frustrated breath, tensing his arms to stop from flailing them. Then he dropped his head back down, and fell silent for some time before asking, "Why can't she learn to have a good life with me there? Why am I in her way?"
