People see things differently and I respect that. I believe she struggled back and forth on whether to meet him because according to LE, they had NO contact in quite some time. Of course, the payphone calls are unanswered because they've gone home, in my mind, to further plan her demise. Probably, her heart told her to meet him, whereas her mind said no, because she had moved on and at one time, feared Tammy. She probably struggled with whether or not to call his cell, for fear of Tammy. I think she sadly trusted him after talking to him on his cell. I think the few unanswered cell calls were either just missed or planned by Tammy as "hey, she wouldn't quit calling". I don't think they realized Sidney was caught on camera at gas station. My point is, even if she called 100 times to the payphone, Sidney initiated the first contact in weeks .... Why?!? Coincidentally, she ends up presumably deceased. She did not initiate contact, he did, and if I were a betting woman, I'd say at Tammy's command (with her in car at payphone I'd guess). I don't think he called to just say hey, how's it going ... But rather meet me, Tammy kicked me out. Of course, just my thoughts and opinions.
