Arnold pushed himself away from his large pig sister. Samantha was concerned, he never refused a hug beforehand, he was always quite welcomed by them. "Arnie *snort*, are you alright?"
Arnold clenched his fists. His voice whimpers out. "Don't call me that... please..."
Samantha was really worried now. She always called him "Arnie". Did he not like that? How long did she not pick that up? It must have been years and she was clueless to it. That made her upset, at herself no less. "I'm sorry *snort* Arnold, I didn't know that *grunt* you didn't like that nickname. We can come up with a new one! How about "Captain"? Or "Arn"? Or "Ri-"
"Stop it"
Samantha was trying to hold in her sadness. She never saw Arnold act like this before. Was he growing up? Wanting to be alone? But he never acted like this before. He was always happy to see her and watch her dance, ever since he was born. She was always supportive and willing to lend a hoof if he needed it. Her ears dropped low, expressing the sadness that she was desperately trying to hide. "We *snort* can talk about it if you want... Is everything *grunt* okay?"
"You... you are not my sister..."
Samantha was shocked. "W-Wh-What?"
"You are not my sister!"
"O-Of course I am, silly!"
"No, you are not! You would always dunk my head in the pool so much so that I was struggling to breathe. You would destroy my things before I would even had the chance to play with them. You would ruin any chances I had of asking a girl out on a date, you would ruin any chances of me having friends, and you would destroy my homework when it would be due... you ruin my life... that's the sister I know... you are not... my sister"
Samantha couldn't hold the tears back anymore. She burst into tears, slowly lowering herself onto the floor, crying her eyes out, giving herself a leaky snout. Arnold silently wept. He wasn't happy to see her "sister" like this. This... this... this pig was trying so hard to be a good sister, but the memories of what he knew his sister to be couldn't make him believe that this was the same body. The same soul. The same sister.
He picked up the controller...
