—Kat, on Rosen's Team
Kat is the newest member of Rosen's Team. Kat is a "free-spirited young loner" who can pick up any skill at a single glance, perfect muscle memory. The only problem is that her memories are very short-lived, and fade within approximately 30 days. Becoming a member of the team provides a purpose and direction for Kat and working with Dr. Rosen, may help her reclaim her lost past. She is an Adomopathic Alpha. Kat is the most tenacious/stubborn in Rosen's Team.
Kat is a white female. She has shoulder-length blonde hair. She is small and looks fragile, but due to her ability, appearances can be deceiving.
Kat is an Adomopathic Alpha, which allows her to copy anything on observation. The downside of Kat's ability is that she retains memories for only a month. It was stated by Kat in "When Push Comes to Shove" that she knows how to do things with no memory of how she learned them. This infers that while she has no memory of events in her past, she still retains any and perhaps all skills she has developed. In the episode "Gaslight" Nina was able to use her ability on Kat to pull fragments of distant memories of her 16th birthday, revealing a tall blonde woman in her life who was believed to be her mother; however, in the episode "If Memory Serves" Mitchell reveals that it was a memory of a commercial that she had seen. Kat was able to draw an exact image of the woman after the experiment and without Nina's assistance. This suggests that in some capacity it is possible for Kat's memory to be recovered.
