The change was so thorough that there was no blood or signs of the injury on her head in just one second. If they hadn't seen everything happen, they wouldn't have believed that she had a heart in her forehead.
She handed the squirming blood vessel to them and said, "This is yours."
Legion wanted to back away from her, but they calmed down first and asked her, "What was that? What was this? What am I to do with it?"
She chuckled in mirth and shook her head as she chuckled. "So many questions. All of your questions will be answered soon. Just take this and put it on your forehead."
They didn't do what she asked for. They continued to watch her warily while waiting for answers to the questions that they asked her.
She stopped chuckling and said seriously, "I am a lamp bearer and your captain. I won't harm you."
She had a point about that. Besides, they had something they could use to nullify any threat to their person if need be. So they took the blood vessel from her.
