This may only make their whining even worse, but they deserve it at this point if they continue to insist on treating conventions as if they’re colifer worshipping sessions. They are a business. Jennifer does not do her job when she backs out of conventions at the last minute. She’s not enthusiastic to be there.
And furthermore she’s made it clear she is done with the show. So white knighting her makes you look pathetic. She’s not thankful, she’s not rooting for you as you defend her right to be Emma Swan forever. She’s rolling her eyes and wishing you’d drop it. She does not want to be Emma Swan anymore.
