Ok ,I am at the end where Todd takes Jessica to the father's cabin and I went to the cave and tried to mix the potion. The stupid stuff wouldn't move so I hit the "skip" button. But it never gave me the potion!! Now the only scenes I can go to are the cave, the dock and the cabin and it says I can't do anything in any of them. What the heck am I missing? And where did the potion go to? Please can anyone help??/ Thanks, Nawahtel
