JJ didn't make an attempt to dodge. Instead, he simply stood up and welcomed the arrow. He had attempted to do this with his own blade before while he was using Despair. If it didn't work then, it wouldn't work with an arrow using the same energy. The arrow merely pinged off of Rage, ineffective. JJ then willed Despair back to him, from behind JT. He attempted to hit JT's left arm on the way back, with the hope of at least damaging it.
