Hmm, if Syaoran was the one who lost his memories, yeah, I think Sakura would be too distrought [sp?] to do anything... she wouldn't be able to concentrate... and as well, since in trc she is a princess, she seems to have less ability... in ccs she was good at athletics which made her be able to do all those crazy moves. So I think Sakura wouldn't give up, but she wouldn't be able to do much...
