Part of Freya really wanted to argue that she'd be fine but she also knew that wasn't the case. Already she was feeling weak again. This was one of those times where she just had to accept defeat. She had done what was necessary to protect those who were seeking refuge at Pimpernel Outreach, Percy was probably back by now....
"Okay, okay. Fine. I'll go home now and rest."
She didn't necessarily like it but it wasn't like there was much she could do about it now.
