Sun Snake:
I think swoft's the only one throwing around accusations and thinking that not only is there definitely a traitor in the brotherhood, but it must be Valador!
Actually Swift plays her cards pretty close to her chest.
Although she occasionally gives away hints of what she's thinking, she does have the ability to just go completely "blank" on the outside and give no hint at all of what sinister thoughts are drifting around her mind.
She has let her guard down a little bit with regards to the rest of the team, but someone like Valador might have difficulty getting much out of her... Unless he can read her mind of course!
