"... Zack?" He glances at Cloud, and has to pause to conjure up pieces of memories mostly scattered and lost. But the conversations were there. Events. Even if he can no longer fully invision those times as they were like a picture faded over time and not a movie he can full recall ... he still remembers enough to answer the question.

"Reckless. Impulsive. Would jump into any situation without fully considering the consequences," which almost sounds like hes just criticizing, "... But he never let his beliefs waver. Even in the face of orders.. That is why when I was assigned to go after them, I refused so Zack was given the mission instead."

He gives a light shrug, but that movement isn't the best idea considering Cloud is bandaging him ... and well his wounds in general. As if he shifts around too much he might make things worse.

He is a little surprised Cloud woukd actually ask. Sure it's natural he'd like to know more, and other than directly talking to the person ... Sephiroth is probably one of the best sources.
