Siblings fight, it's only natural. You and Ace were no different. Insults were thrown (as well as other more... physical things), but it never got too serious. At the end of the day, he's your brother. So after the mandatory ~~bullying~~ teasing, he dragged you away to deal with your injuries.

"Man, how'd you get this busted up?" Ace laughed as he pressed a cold cloth on one of your many bruises. "FYI, you owe me for this. But seriously, it's like you took a nose dive down the stairs! Knowing your clumsy ass, I'd believe it," Ace waited for a response. And waited. And waited... Jeez what's wrong with them? No quips or comebacks? He started to get the feeling that something was wrong.

"Hey, what really happened?" He kept a smile on his face, but you could sense the worry behind it.
