Re: The OFFICAL Kiba and Akamaru FC
I think he was afraid of how violent Akamaru was. Also that the medicine had a 50/50 chance of working and was afraid that it may not work and that he didn't want to kill Akamaru.
If you remember back when Kiba was fighting that sound-nin, when Kiba thought Akamaru was dead and tried to kill himself. When he said "i'll always be with you" and braced him self for the attack, I think he was willing to die with Akamaru.
Bitter Sweet isn't?
Has been and has come back again....
