As some people know, in "the Cosmo conspiracy" episode, Tails had to kill her to save the galaxy. This was clearly hard for Tails, because he had grown feelings for Cosmo. In the Japanese version of Sonic x, Tails had shouted, 'I love you' before he shot Cosmo. And in the end she also said, 'I'll love you forever'.
