The knowledge of a betrayal.

Severus wanted to tell Scarlet but she had slept off by the time he concluded his realizations and solidified his theory. The hound figured then, that it could wait. Tomorrow, he would tell her. 

When morning came, they were not woken up by any rising suns or chirping birds. The sound of hammering coming from somewhere inside the space ship was what got everyone to rise. 

An exhausted Scarlet groaned unhappily and pulled the covers of the bed up to block out the pounding noise. Not only was it annoying but it was also frighteningly loud. To her ears, it almost sounded like thunder roaring on a rainy night. 

The warm blanket which she covered over her head didn't work and she was forced to open her exhausted eyes. 

"Oh-hooo." she sat up and threw the covers aside. "Make it stop." 

"Or block it out using your powers." Severus suggested.
