The Companion is the physician to the channel.
(Source: Index card file. "Companions abilities" -- Notes on Sergi -- May 10, 1977) Gen might recognize Need from outward symptoms, and body might be responding to it, but probably wouldn't know what his responses meant until he Qualified.
Only Four-Plus feel their body responses consciously. Normal human empathy might make Gen think he "feels" the channel's need. Donor would prefer a higher need and could feel a difference in transfer, but couldn't verbalize it --- just "happier." All good Companions have high empathy (intuition) and seem to have (and may have) telepathy -- but only as sensitive ancients, as Jacqueline and Jean.
May 19, 1977 --- No GN class donor --- not GN-3, GN-2 or GN-1 --- can survive any non-channel transfer. The FACT that you can survive a renSime's Killmode attack is the Qualifying TN-3. All Distect Gens are at least TN-3 and most in-Territory Gens are TN-3 within a year or two of establishment. TN-3's's are the normal run of humanity --- only psychology, culture and FEAR keep out-Territory Gens from Qualifying.
A person who would use a weakness against someone is a person whose whole psychology is based on fear --- would be a prime victim, a GN forever.
June 3, 1977 --- First three transfers crucial in setting the limits of a Donor's development.
(Source: Index card file --- CARD MARKED "COMPANION FUNCTIONS" -- from FIRST CHANNEL) Actually the powers of Gens discovered by Kadi. (1) can FORCE selyn – actually GIVE selyn to sime. (2) can calm a sime in Need (3) makes a renSime laugh. Kadi’s amusement goes from forced (to make the renSime laugh) to REAL – whole world seems funny. (4) can change a sime’s level of “consciousness” from hypoconscious to hyperconscious to duoconscious (when Rimon is stuck hypoconscious after transfer). (5) Supports Rimon in healing a sime. When Rimon and Kadi are together, no one can tell where Rimon is in his Need cycle. (6) Kadi becomes transparent, visible to sime senses only as a brightness. When Jord is zlinning her, Rimon doesn’t like it.
