“I would say this theory makes it official that this show has the greatest viewers and fans around,” Gimple told Yahoo TV. “I would say I would desperately like to live in a world where Daryl Dixon intimately knew Morse code, and intimately knew that Rick knew Morse code. I’m not even kidding. That is completely badass.”
“I will also say it was an incredibly sunny day,” he continued. “Also, Andy [Lincoln] and Norman [Reedus] are really close. I think the theory actually could be correct, but not within the story. Meaning, I don’t put it past those two gentlemen, who are now so unbelievably close, that maybe Andy and Norman were communicating with each other, like they were saying, ‘Oh, that was a good take. I really like what you did there. You’re really bringing it.’ Or, this could be a whole ruse, and there was Morse code in there.”
The theory goes that, based on the blinks seen in this GIF, Daryl appears to be telling Rick “I-E-A-S-T” or “I East.” Fans believe Daryl is telling Rick where The Saviors’ compound is located.
Other theories suggest that Daryl is spelling “6 miles East” or “East of Hilltop.” No matter what, they all contain the word “East” in one way or another.
