A jolt of fear hit him. Evanlyn! What had become of her? He remembered, as if through a fog, that there was some great danger hanging over her. Her identity must never be revealed to their captors. Had they actually reached Hallasholm? He was sure that, if they had, he would remember. But where was the green-eyed blond girl who had come to mean so much to him? Had he inadvertently betrayed her? Had the Skandians killed her?
A Vallasvow! He remembered it now. Ragnak, Obetjarl of the Skandians, had sworn a vow of vengeance on every member of the Araluen royal family. And Evanlyn was, in reality, Cassandra, princess of the realm. In agony of uncertainty and lost memory, Will pounded the heels of his fists into his forehead, trying to remember, trying to reassure himself that Evanlyn had not suffered because he had somehow failed her.
And then, even as he thought of her, the door of the cabin slammed back on its crude leather hinges and she was there, framed against the bright sunlight reflecting from the snow outside and as breathtakingly beautiful as he knew he would always remember her to be, no matter howling he lived or how old they might both become.
He moved toward her now, a smile of utter relief breaking out across his features, holding out his hands to her as she stood, wordless, staring at him as if he were some kind of ghost.
"Evanlyn!" he said. "Thank goodness you're safe!"
And, saying it, he wondered why her eyes had filled, and why her shoulders were shaking as tear after tear spilled uncontrollably down her cheeks.
After all, he couldn't find really see that there was anything to cry about.

(This part is in the Ranger's Apprentice: The Icebound Land book. I own nothing and none of the characters. I also haven't read beyond this book yet. I'm making a fanfiction of these too mostly. The only parts I'll own is what doesn't happen in the actual book.
Again, I haven't read books beyond this. I have no idea if the parts I think of will be in the next book or not. I give credit for the amazing John Flanagan for writing this series. You can check out his books if you want too.)
