[At some point, the Tetsuo from Kaneda's time must have gotten access to Kaneda's glove compartment. The next time Kaneda roots around in there - maybe for tools, or a map, or some stray bits of odds and end keepsakes, there's something that he won't remember.
A carefully folded piece of paper, with surprisingly legible handwriting for Tetsuo.
Unfolded, it's a letter. It's been written, rewritten, and rewritten again in pencil, hastily erased at points. It's not going to win any prizes for composition, or legibility, and not remotely for coherency, but it's quite possibly the most sincerely honest, and heartfelt thing that Tetsuo has ever done... and possibly will ever say.]
