"Then put up with it. It's not like you are strong enough to stop me."
"When eldest brother returns with big sis, I will use my killer move. You're sure you can handle the consequences?" she blinked her eyes provocatively at him while wearing a knowing smile.
Peter sighed in defeat and flew out the window. He knew too well the consequences if she used that move. The last time she did so, he got posted far away to fulfil a task. He was very lucky to make it back. That's the reason he, in the name of training, wanted her to suffer a bit while keeping track of her safety.
How long had he come back from that mission? Nah, he's not doing another so soon.
So yeah, he must swallow down his pride or, as his kid sister said, he'll have to handle the aftermath. Deep inside, he's still not reconciled!
