I don’t think that August called Henry. The tone he was using with the person on the other end of the line was quite different from the tone he has used with Henry in every scene we have seen them in together. I was thinking that he called Bae and it was him that suggested he focus his attentions on Mr. Gold/the dagger. The only thing is, Bae would have told him that trying to use the dagger to control his father wouldn’t work. Mr. Gold said himself that his son would never try that because he knew better. Unless Bae thought it might work because Emma has magic, so our world isn’t “without magic” after all. It would also make sense that it was August’s idea to look for the dagger and he was so desperate to live that he ignored Bae’s advice to focus on Emma and not Mr. Gold. I can’t believe I’m racking my brain like this over a television show. I haven’t concentrated this hard since college….well, since Lost.
