As the Princess confessed her love, Casper felt like something was squeezing his heart. His emotions weren't converging. One side of him was glad, the other was frustrated and in pain, though.
He wanted to state the same. The soldier wanted badly to tell her that he felt like that as well. However, for a moment, he couldn't bring himself to say something like that. Not when all his past was flashing on his mind again.
He didn't know what was more painful: watch Vick in that state or remember his past love dying in front of him and all the good moments that they had.
Vick returned to hug. There was no lust behind their acts anymore, just fondness. They both were finding support for each other.
