It isn't as if Teagan expects anything or anyone pleasant down here. That this woman answered is all that she could hope for. That he's 'fine' is even better.
Teagan does know how much Solomon Reed has risked but she isn't sure it's all for Teagan. Sol seems to have a sense of justice that outshines the kind that an outlaw like Teagan has. The code she lives for is a more selfish variety but it doesn't mean she can't appreciate what Solomon and now his sister have done for her.
His sister. It's an assumption. A guess. She's seen the interview between Nate and Sol. She's listened to Jo. Heard stories about the Reed's.
"Thank you. Thank you for bringing this down to me." It's the least she can offer and it doesn't mean that it's all she will ever return. She knows she owes them big time if what's in this folder is valuable to her purposes. Teagan doesn't waste time opening what is given and evaluating the contents. It's everything she wanted...needed. "I owe you two big."
Teagan glances over at Torrie and sees that the woman doesn't have any idea what she means or why she should be enthusiastic about the contents within, "It's proof that I aint a rat. It's proof that Olinger is a snake and one of my dear brothers fucked us all over."
