Leela and Andred's first child

According to one account, Leela and Andred's first child, half-human and half-Time Lord, was the first child conceived naturally on Gallifrey since the Pythia's curse of sterility which had originally forced the Great Houses to develop the looms.

Noting with a twinkle in his eye that the son of a Time Lord father and a human mother would make for "interesting parentage", the Seventh Doctor, upon learning that Leela was expecting, advised her to name the child after him. (PROSE: Lungbarrow)

Behind the scenes

 * One possible interpretation of Lungbarrow is that Leela and Andred's child eventually travels back to the Dark Times and becomes the Other, thus reconciling the idea of the Doctor being half-human with that of his being the loom-born reincarnation of the Other.
 * The Faction Paradox character of Intrepid may have been intended to be an older version of Leela and Andred's child, being highlighted as half-human without their parentage or birth name ever being clarified.
