Usually, they started out sick.
There it would stay, as well, until someone was bitten by a deadly Tovè’s Viper or shattered all their bones by falling from the top of a cliff onto a moving speeder.
There was also a tube of “stillpoint gel,” a remedy peculiar to Jedi, that Obi-Wan seemed to find helpful. At least, he kept asking his Master to put new dabs of it on the insides of his wrists.
Sympathy pains jabbed Qui-Gon’s own gut whenever Obi-Wan had another spasm of vomiting, especially when the boy reflexively gripped that sore place, but the Master Jedi also felt compelled to watch from a bit of a mental distance and evaluate how the child was coping. From the very beginning, Jedi prepared themselves for the end—and the little one sitting on Qui-Gon’s lap was already learning how to withstand pain and face down fear.
He *was* being extraordinarily contrary at the moment, but being disagreeable was one way of killing the demoralizing whispers of pain.
Qui-Gon had known Obi-Wan since he was pulled from the ruined city of Ixaca as a three-year-old—a lad too Force-blessed to have been killed and too stubborn to give up and die.
One couldn’t argue with a nasty infective agent, after all, and that left one’s Master by process of elimination.
The feel of the boy’s sweat-dampened spiky hair against his cheek stirred up feelings too fundamental for Jedi training to root out, however.
Obi-Wan might have discovered gallows humor, but apparently in moments of crisis he still thought of adults as being like the basic forces of the universe—absolutely reliable and not necessarily sentient.
