It wasn't an uncommon occurrence for a knight to be out in the heat of battle. Especially for Nicholas.
After all, he was one of the highest ranked guards in the castle itself; often stationed just outside of the Queen/King's quarters. Only in this instance he was not guarding the royal family but fighting a heated battle.
But for him to come to your aid after getting seriously injured on the front lines was something completely out of the blue.
Limping to a halt just outside of your bedroom from the outside of the castle Nicholas stood, a hand clutching his side. While he wore a thick, sleek suit of armor, you're sometimes bound to get injured despite the security. He wore thick wrapped bandages from his ribcage to his hip, a temporary fix.
He knocked somewhat firmly against the window to your quarters with a grunt, panting heavily against his helmet. He gritted his teeth, trying to remain quiet in the dead, soundless night.
"Who is it at such a late hour-"
He heard you grumble, only to gasp in shock at his form. More specifically the particular stains on his suit.
"I-I apologize for coming at such a late hour, princess/prince, but-"
He muttered somewhat quickly as he already started to make his way closer to you.
