[ all helen really manages to give in response to her clinic is a smile before rebekah makes her question. on the one hand, it's an innocent enough question. if matt really is a friend of rebekah -- and she sees no reason why rebekah would lie about that, if asked -- there's no harm in answering a simple yes or no question. however, there's also the idea of patient confidentiality and with it comes the reminder that helen doesn't really know anyone here except nikola.
trusting any of them... that's another step. despite only having known rebekah for a few days, helen likes her and because of that -- ignoring the cautiously calculating look she's been giving rebekah for a few seconds -- she's been willing to entertain a friendship with the other woman. ]
