Regarding Sin#6, I'd also say that Leshawna already got her revenge on Heather at the end of last episode.

I'd also add a sin for Leshawna shredding Heather's clothes off-screen becasue A. bullying, B. that's not what her revenge was like last episode, C. it means she's taken two revenges on Heather at once.

Regarding @in #10, no they're not gender separated. From the design of its inside and scenes inside it in several episodes, it appears girls and boys only use them at different times, but can enter at the same time if they'd want to.
