Okay after seeing both the US & Canadian Promo’s for Selfless, Brave And True Here is my speculations & Theories about Tamara.
I am changing my position on Tamara originally I thought she could just be an ordinary normal person from this world now I’m not so sure I think there is definitely more to her character. I have the feeling that she knew August and who he really is and if that is the case then I think it is entirely possible that she and August could have worked together to get Henry to Storybrooke when he was born. I think Tamara may have spied on August’s & Neal’s meeting in New York. I’m beginning to suspect that Tamara could also be Greg’s mysterious “Her” I don’t think she could be Tinkerbell but I do think Tamara could possibly be a fairy who maybe wants revenge on Rumple for a past wrong. We know that Rumple has killed faries before in the past and one way to get revenge on Rumple would be to go after his son who escaped to this world before the curse.
