The hesitance in his movement in opening the door was enough to let Sakura know Sasuke was serious about his reaction to dying. Not that she expected anyone to be happy and immediately normal again after a reincarnation, but she had never in her life expected to see him of all people behaving the way he was. Not now, anyway.
Walking inside, she turned once well into the room and stared at the condition he was in. Blood still remained splattered against his torn clothing. The sight of excessive blood was nothing new to her but she could not help look immediately concerned, her face contorting into an expression of definite worry. He looked like he was still in... disbelief.
Quickly returning to where he was standing instead, she examined him with her eyes for any signs of cuts, bruises, or broken bones, but she didn't see any. Well... not that there should have been since he was alive again.
