Axel could tell something was wrong. He just didn't know what.
After he checked Roxas's room, he was feeling okay.
Then he checked Xion.
She was tossing and turning violently and almost falling off her bed.
Axel ran over, picked her up and hugged her gently.
When she woke up, she cried into his chest.
He had to keep repeating, "It was only a dream, Xion, nothing more,"
She told him what happened and fell peacefully asleep in his arms.
He placed her gently back on the bed and walked back to his room.
He lay down, saying;
"Mission… Accomplished."
