Michael push a pregrant Justin down the stair

[loahisi]

  Hi, I'm new to this community but I already read a lot of fic you rec. I check the anti-Michael tag but I didn't find the story I wanted. Like I said in the subject, all I remember is that B/J are at Debbie's and Michael push Justin down the stair. He's pregrant but I'm not sure if the gang is aware of it. Brian freaks out because of the baby. And that's all I remember. Hope you can help me.

PS: I'm not English so bear with me, please!
