How to RescueEdit
Switch to Juliette via the Telepoint near the bookcase if you have not already done so. Climb the wall via the Cat Scratches on the bookcase. At the top shelf, leap over to the other shelf then onto the chair. Leap up to the two buttons and press them. When the chair back has risen, climb up the Cat Scratches to the top. From here, leap down to the nearby globe. Then, as the globe starts turning, use the Beaver Dam model to leap onto the Cat Scratches on the handle and climb up to rescue Gerard. Or you can simply run up to the Cat Scratches and climb them.
