Kelsey is an autogirl- an artificial service humanoid- with a bad back.
Trice is her medichanic, a combination of mechanic, physical therapist and nurse.

Kelsey is going to get taken apart and put back together again, all fixed, and it's not like she has a huge crush on Trice or a fixation on her strong arms and clever fingers and it's not at all like she dreams of getting pinned down and... well, it's not like that.

Even though that's more or less exactly what's going to happen to her.
