ep1 level 2

ground pound on the pressure pad with daphney

He follows her through almost everything she does in the library, there are a couple of times where you have to switch characters so Fred can crank the switch, but mostly you don't have to worry about where he is he just follows along. Or she has to pull a switch etc. For him to come through a door, but it's pretty obvious. The first activity is Daphne climbs a pipe by the first door, jumps over the top of 2 bookcases to the third to pull a level to open a door on the other side of the library for her and Fred to go through.

The place I think you are referring to is where Daphne has to climb another pipe (the standard pink light running up & down the pipe) leaving Fred with no way over a gap. She jumps off on the other side of the gap and there is a red pressure pad. She "thump-jumps" or "ground-pounds" which ever you call it and a bridge will lower for Fred. I am pretty sure through the rest of this Episode and level he just follows after her where ever she goes, or they work together.
