Lydia wasn't exactly being subtle. She didn't supposed she had to be, really. Sara looked back up before going back to work, but she wasn't ignoring Lydia, so the redhead thought that a neutral response; at least she wasn't shutting it down. When Sara spoke, she wasn't asking. It didn't sound like she was, anyway; it sound liked she was reflectively listening. So Lydia nodded.
"...yeah," she admitted. If Sara was an advocate for women learning new ways to take care of themselves and she also knew how to defend herself, logic would dictate that Lydia wasn't really fighting an uphill battle or anything, but it was still something Lydia was getting used to: asking for help.
Back home, Lydia seldom did. She trudged through everything on her own until someone forced themselves in — usually, Allison or Stiles — but she was fast learning that she couldn't do that forever. She certainly shouldn't be trying to do it here. Lydia's lips pressed together and she shifted her eyes back down to her work. "I don't know any of that stuff. I know a lot, but as it turns out, not a whole lot of it is useful outside a chemistry lab or a classroom. Things back home...they're kind of crazy. ...really crazy... And Allison isn't around anymore to save me. Eventually, I'll have to go home; I don't think we're meant to stay here forever, right? So...I need to learn how to save myself and I just thought, you know, you'd said..." her voice trailed off and she shrugged. "You're busy, though, I get that. You're one of the people who actually knows what they're doing here, so I'm sure you've got a lot on your plate. I just thought..." she paused and took a deep breath, letting it out in a soft huff. "If you got some free time."
