I agree with both of you and Oh, I do wish we could discuss those other reasons; I have 'em, too! :/
By calling (demanding) that JC come over to her, I think CigLady (lol, I like that) knowingly stayed out of camera sight. In this instance, I think calling someone over to you to just "bum a smoke" is a controlling or manipulative behavior and it's been discussed here that it may have been a ruse given that she turned down the offered cig. (who does that?). You want to talk to me - you come to me. I'm not a dog, I won't come on demand. JC did not look/act thrilled to see whoever it was that called to her (before we knew who it was and the relationship).
Of course, this is just my opinion and it is oh, so colored by my own life experiences.
