However, everything changes for Fred when she and the rest of Angel's crew join Wolfram & Hart. (While Angel accepts a suite of rooms at Wolfram & Hart as his new home, Fred, and maybe others of the inner circle, find a home in the Los Angeles area: hers is at 511 Windward Circle. This seems to be forgotten with the advent of Illyria.) Her memory is altered by a spell cast in Season Four's last episode, " Home ", and it is unclear how much of the events of Seasons Three and Four she remembers differently or at all (everything specific to Angel's son Connor is definitely lost). Fred receives her own laboratory and becomes the head of Wolfram & Hart 's Science Division. She is a major asset to the team; Angel consistently relies on her department to quickly and efficiently solve problems. After going on a few dates with co-worker Knox, Fred begins to have feelings for Wesley again. The pair are together for about a week, but the couple's happiness is not to last.
