A Jack Wells Production
Recently, despite several warnings, Bruce hit his big brother, Clark, with a batarang. You say it happen, so Bruce couldn't deny it. He did insist that he only did it because Clark was being criminal and deserved it (13-year old Clark claims that he locked the bathroom door because he didn't want 'the twerp' staring at him while he used his acne medicine and let him in as soon as he knocked).
The batarang is foam, so it doesn't really hurt, but you don't like him throwing it at people (especially when he's mad), and you've warned him about it. In response, you put away all his Batman toys, and told him he was restricted from playing Batman until the weekend.
