When Benden Weyr first rose to fight Thread, Gereth was the worst injured; one of her wings was shredded to bare cartilage. Lessa walked past them while tending to the injured, but had to look away from the "misery in B'fol's worried eyes".
B'fol and Gereth were the watchpair at Benden Weyr the night before F'lar and Lessa travelled to Landing for an early morning meeting with AIVAS regarding their next move in the plan to destroy Thread once and for all. Lessa discovered that B'fol and Gereth had fallen asleep on duty, and F'lar sent Mnementh to wake them by roaring at them. Mnementh remarked that they wouldn't repeat their mistake - Lessa noted they were "well enough on in turns not to be delinquent" - and F'lar planned to punish them further by making them handle Firestone sacks in the next Fall.
