can you give me a walktrough or save game..?Ok, those screenshots did'nt help at all.
this is my generic answer:
There are many steps to get past Claire so it depends how far you are into the game.
As a general hint:
1) start with Dana
2) Follow the trashed classroom with Janice.
3) Continue with both of them to the demonstration
4) Follow the missing teacher to Hannah
5) Investigate the catfight at the gym
6) Talk to your sister Mia, to your other sister Lisa and your Mom.
Use the hints (there is no limit) and ask CAS why the game is so difficult to get a general idea how I think it.
Cheers!
