She was never assigned a watcher before her arrival in Sunnydale, and thus never knew of her possible destiny. She often doubted that she or any of the other potential slayers could make a difference and even stated that there was no point in the potentials fighting. During the Battle at the Vineyard (her first), her arm was broken by Caleb and she would've been killed by a bringer had Xander Harris not saved her. She wore a cast throughout the remainder of the series. In the Battle at the Hellmouth, she slayed several Turok-Han and at one point used Buffy Summers' Scythe to do so. She received several wounds but ultimately survived, escaping aboard a school bus.
As the Slayer Organization was formed, she became the leader of the Chicago squad, where the Buffy Summers underground decoy originally joined up. Rona was the one to offer her the assignment as decoy. Later, due to the constant difficulties with Simone Doffler, Rona transferred her to Andrew Wells' squad in Italy with the hopes that a less urban setting would soften Simone's "rough edges;" Buffy later speculated that Rona was just "passing the buck" onto Andrew.
