Isabel could tell Rodney wasn't exactly thrilled by her 'I can take care of myself' response, and that Carson didn't really seem to understand it, or maybe he just thought she was being stubborn. She couldn't explain to them how she protect herself, so she kept her mouth shut. She'd spent her entire life hiding her secret. That wasn't going to change while she was...well, wherever she was.
"...Carson's from Scotland and I'm from Canada."
"I'm from New Mexico..." She stopped talking when Rodney said something about Ronon. She was about to ask exactly what Ronon was when she looked off into the distance and saw another person.
Hope flared within her. If someone they knew was here, maybe someone like Max or Michael was here as well.
