"ELSA!".
He stood at the door and called out to her who is layed on the bed and surrounded by men and women in armor, all with cheerful expressions on their faces.
Hearing the voice that came from the door, the armored men and women made way for the figure to pass through, leading directly to Elsa who is still on the bed.
"my lord".
She heard the voice and turned her head to where it came from.
Elsa called him by his title, while attempting to stand up on her feet and greet him like a proper knight would his lord.
Thomas realized what she was about to do, and he hurriedly ran toward her to stop her.
She has just woken up, and needs time to connect with her body. Putting it under further stress could lead to more complications for her, and he does not want that.
The knights who were closer to her, they wanted to stop her, but they could not. Getting in the way of their captain fulfilling her duty, is not their call to make, but that of their lord.
