 FACT: In the opening, Annie (the third person) was belaying Peter  (the second) up the pitch he was climbing. In a three person rope  team, the leader would belay the second person up, not the third.  Because Annie was belaying Peter, Peter was essentially on lead and  should have been placing protection on his way up. In addition,  since his father already led that pitch, the gear that he placed  should have still been in the crack.
