As Devin was embracing the girl in his arms and caressed her back with his free hand, Angeal had already calmed down. They have been in this position for 10 minutes but the Soul Eater didn't mind it. He wanted Angeal to feel better.
As Angeal's head was resting on Devin's chest, she heard his heart beating. It was slow—steady... giving her a sense of clarity.
This made the girl realize that their master is indeed alive.
'Alive,' the girl thought as she abruptly looked at Devin, remembering what was said to her about the curse.
Eating the souls of other people forcefully is considered murder... so it lessens his lifespan.
The girl's eyes turned sad and her eyebrows showed worry. She lifted up her hand, held his face, then mouthed something, making the Soul Eater look at her with bewildered eyes.
"Are you okay?"
Devin blinked his eyes a few times then raised an eyebrow at her.
"Why would you ask me that when you are in this situation?"
