Biography
Senta put Nanina through the transference process when she was brought in by Exorse. He was surprised when Dodo Chaplet showed up in the laboratory and wanted to report the matter, but Edal ordered him not to do so.

Senta also performed the transference process on the First Doctor, transferring his life force into Jano. Edal convinced him that the transference was making Jano behave strangely. However, when Jano returned and began destroying the machinery, Senta was powerless to stop him. (TV: The Savages)
