I think that it might be Rukia as well. The image he saw when he was overcome with fear last time was of Rukia essentially dying. With her being right by his side, if he doesn't kill Äs, Rukia will die. It would be ridiculous to be too afraid of someone dying that you can't even attempt to stop it from happening.
