That was... Uhura didn't know how to react to that except for the rather sharp dagger of concern that was launched through her heart. It was surprising, really, to see what she did in Kirk's eyes, but it was impossible to deny. She knew McCoy was his best friend, that he'd hate to see him hurt, but what could they do? They were centuries before the people on this planet had even heard of the disease much less made a treatment for it. Not that it would have done any good with a terminal case, anyway.
But still. It would have been better than sitting there and watching a four year old languish away for the second time in as many years.
Swallowing slightly, Uhura pushed herself from the chair that she'd sat down in and crossing over, settling down next to him and resting a hand lightly on his shoulder. "We'll figure something out," She said gently, even if she knew that it was likely not a possibility. "I mean, there might be something here that was wiped out by the 23rd century that will cure it outright. We won't know if we don't try."
