Kirito actually could not even lift his arm , he tried to lift his arm but only managed to lift his hand then slowly moved in front of his body and face,he could see his veins thru his skin and saw the IV line, followed it , looked at his surroundings and still not sure where he was and then motioned his left hand to check and nothing happened.
Thats when he realized that he has returned, but he died in SAO and then he remembered what Kabaya last told him that he and Asuna cleared and thats when he tried to say Asuna but his throat hurt and then he still was confused if everything was just a dream but he realized that Asuna exists and felt a need to find out if she is back .
He tried to get up ,but his head was still strapped, Something was heavy on his head but barely managed to take the nerve gear helmet off. He struggled to sit up and looked at the helmet ,
Then he heard commotions ,footsteps, wheels. He pulled of his lines off, tried to get up, but his knees buckled, but his need to find Asuna made him gather more strenght , grab the IV pole and took his first step to the door .
