New series maybe?

This is the premise for a new series I want to write... not really well thought-out or edited... just something I wrote during a plane ride.

"Don't kill me, please."

My eyes narrowed as I flopped down on my bed, wondering what my little brother's girlfriend, Erica, got me into this time. "What did you do?"

She hesitated, trying to figure out the best way to break the news. "So remember that song you wrote and I was recording...?"

My cheeks flushed, self-conscious about my horrendous music-writing abilities. I shouldn't have shared that song with her... "Yes, what about it? You were going to delete it because it's not YouTube-worthy..."

"About that..."

"Bro, what the fuck happened?"  I'd been upstairs studying for hours, only taking a break when I heard my stomach growl.  In the living room sat a black-eyed Tristen, surrounded in a semi-circle by Toby, Izaak, and Molly.  Tristen was still shaky, bag of frozen peas in hand, nervously fiddling with the plastic as she tried not to look at anyone.

"There was an altercation," Toby said, guiding his little sister's hand so that she would put the ice on her wound.  I noticed scratches on her arm and a few bruises.  

"What?  Who?  Did you call the cops?"

Tristen's one eye got really wide.  "No!"

"Why the hell not?  Who fucked you up like this?"  She stayed silent, looking back down at the floor and started crying again.  I glanced from Toby, who seemed more concerned than annoyed, to Izaak and Molly.

"She won't tell us yet.  She's too scared," Molly said softly.  

"Scared of what?" I said, so loud that it made Molly flinch a little.  So I toned it down as much as I could, considering the way my heart raced and I felt the urge to knock someone's teeth out.  Looking back at Tristen, I asked, "Are you being threatened?"  

She shook her head, still not looking up.  If I wasn't so pissed, I would've taken a moment to appreciate her cute submissiveness, but right now it was fucking annoying.  That's how she got herself into this mess in the first place. 

"Well what is it?  Come on, tell us."

Toby shot me a glare.  "You're not being helpful right now."
