When the redhead waved, Lydia lightly and confusingly waved back at her. She watched as she took a seat next to Mitch and started talking about what she was going to order. So, when Mitch asked if she had invited her, she shook her head. "No... Kinda thought you did, until you asked me that..." She said. Only to look out the window and look down the streets a moment.
No Stiles or Scott. Good. So, her focus came back to Jaz as she tilted her head. "Um..." Lydia was actually caught off guard by the woman and her joining them for lunch. "I mean.. I don't mind if you don't?" She said towards Mitch, who was glaring at Jaz.
In truth, it looked like something Lydia would have done to Sciles (Scott and Stiles) if they just showed up on a lunch she was having with a friend too.
