"God, you've always been like this! That's it! We're taking Arthur to the mental hospital, now. Seamus, you hold him down from the left, I'm getting the car!" Allistair, eldest of the Kirkland family yelled as he grabbed the car keys from the floor, currently covered in disorganized papers. He was quick enough to remember that Peter was in the house. Arthur could hurt him, or mentally scar the seven year old boy with his insane words. He can't let that happen again.
Before proceeding to the car, Allistair dropped his coat and dashed to find the youngest Kirkland. The last time he left him alone...
No. Most definitely cannot let that happen again.
Peter was found under his bed, trembling and covering his ears. Frightening, was it not? Seeing your loved ones go insane slowly, slipping away from you. Those who have slipped can scare you into slipping as well, and it's the inevitable truth that most do.
"I'm sorry, I'm sorry, I'll do as you say, don't tell him where I'm hidin-"
And that, was when Allistair finally snapped. Arthur had done enough to frighten Peter like this, he had enough.
"Peter, run. Run away from home and don't come back until I do come for you."
He obeyed.
