My guess would be Terezi not being in an abusive relationship with Gamzee.  Without Gamzee keeping her secluded, Terezi would have been had the foresight to know what excessive drinking would do to Rose thanks to her Seer powers and been able to help Rose or prevent her alcoholism from happening.  Kanaya didn’t stop Rose from drinking because Kanaya didn’t know it would become an issue until it was too late.

The Queen’s ring with prototyped orbs has no effect on humans.  But the post scratch Queen’s ring is a very distinct type of ring not normally found in Sburb sessions.  It is a Ring of Void which is usable by humans.

Null Sessions can be scratched.  Rose also explains that Null Sessions are fairly common here.

Jade remembered that she was asleep and not dead.  Vriska has the power to put humans to sleep.  Vriska is still alive.  Vriska put Jade and Jane to sleep.

Originally Rose is leaning on Kanaya because she was hungover

In the retcon timeline Rose is standing on her own so it can be assumed that either she never became an alcoholic or that she overcame it before arriving.
