Shisui sighed and considered Itachi. Shisui was an inch or so taller than him, definitely heavier, but there were similarities. Coloring, cheekbones, wiry build that was better for speed... Really just Uchiha-based similarities. He could say the same (and more) about any other Uchiha. But this brat happened to be his best friend, as much as he cared about the rest of them. Of course, that had nothing to do with appearance, just the fact that Shisui had been a handy family member to watch over a toddler Itachi and try to keep him from dying or getting hurt or harassing their aunt's cat.

Shisui shook his head with a grimace. He was going senile--twenty-four and thinking about his long gone past.

"Shit, Ita, in a couple of months I'm going to be halfway to thirty."
