There are six extra cases from Olivia, three in each episode. Every time you need a specific item for an extra case, the item will be a shining point with no observations.
EPISODE 1
1) She requires the crew manual. Turn around and go forward once, then turn left. The manual is on the seat.
2) Next, she requires a toolbox. From Olivia, go forward twice so you're just before Deborah Anderson. The toolbox is in the overhead compartment to your right.
3) Finally, she requires a specific blanket. Move just before business class, where Cheney blocks you from going further. The blanket is in the overhead compartment to your right.
EPISODE 2
4) What's the capital of Brazil? Turn around to the cargo compartment you were just locked in. The world map is on the floor.
5) What Bond movies starred Timothy Dalton? Exit the dive, then move to the end of the hallway and turn right. Looking from here out the living room window, the item is on the bookshelf to your left.
6) Cafe au lait and cafe latte? Exit the dive, then move into the kitchen. The item is next to the coffee maker.
