Fleeing in general leaves the backside open, but he can leap high enough anywhere or over them if necessary. Cloud has his own fancy moves but he's not about to go all out without seeing what the other's motives are.

Cloud watches the bugs while keeping to their sounds. His senses would stay sharp as he focuses back on Nathanos. "Nathanos Blightcaller of the Horde?" Did he hear that right? He frowns while shaking his head at this claiming territory. Cloud stays where he is not coming close or making any move to flee. He keeps his eyes on Nathanos while waiting to see what the other might do or say next.
