"There are plenty of things I know for certain." Debra half ignores Bethan right there, mildly embarrassed about the entire hospital thing and so far tonight, not to mention the ridiculous swell of her current crush on Dan -which is highly inappropriate since Bethan is currently Dan and the whole hospital thing was partially to blame for the size of this...infatuation. And it wasn't even Dan!
"I know for certain that I will never compromise my morals for a tabloid gossip rag like Jacob ben Israel. I know for certain I will never stop missing my Nana. I know for certain the Earth rotates to the East and that lemmings are not suicidal like redundant video games like to imply." Debra was mostly just being difficult, but she didn't like the idea that Bethan was countering something that they both knew was true.
It was the comment about her concern that made her turn back in her seat. "Are you saying that if I openly showed concern for your well-being, like I have several times, you wouldn't snap my head off for even implying that you can't take care of yourself?" Debra made a point of not vocalising that she was steadily growing more worried for Bethan's safety every time she went out. It wasn't because she thought Bethan couldn't handle it, but there was the niggling feeling that sometimes Bethan purposely put herself in harms way. Not to mention Debra counted Bethan as a friend and continued to worry about her anyway.
