Spoiler's for those who aren't far into the game.

Playing as Christine I was required to use the 3 keys on the fridge, as well as give the bird book to the priest to send back to Joe, however i used the keys on the fridge and it switch to me to Joe. Now, I CAN'T SWITCH BACK TO CHRISTINE AND I'M STUCK WANDERING AROUND LIKE A BUFFOON WITH JOE, the bird book has not been sent and i have no idea what to do about it.

It's possible i'm missing something, but at the moment it seems that for this atleast, if it's not done in the right order the game is over, dead end save file.

If anyone has any suggestions please let me know what to do.
