There's a Fusion version of me who took Kenji as a hostage. Now she refuses to let him go, unless I hand her over a datachip Six gave to me, which I refuse. It's not far. That's why I need you to save him.
Good, Rex did very well, but you can't give it to me now; Fusion Yumi still wants it. So you have to hide it in Mount Blackhead, but don't give it to Ed, because he's too dumb. Give it to a smarter being to protect it.
