They weren't allowed to talk to each other but did they manage to communicate on the sly?

SPOILER ALERT: Spoilers for season seven, episode four of The Walking Dead follow.

The fourth episode of The Walking Dead’s seventh season saw Daryl return to Alexandria alongside Negan and the Saviors, who were there to collect their tribute. It was here Daryl saw Rick and the gang for the first time since Glenn and Abraham had their heads caved in by Negan’s barbed wire-covered baseball bat, Lucille. During this episode, Daryl didn’t say anything at all – but fans of the show were convinced he was communicating with Rick somehow.

That’s because of the early establishing shot in Rick’s house shown above. A table guide to American Morse code hanging on Rick’s wall suggests he and Daryl may have been using Morse code to communicate with one another. Daryl has in the past learnt a bit of Morse code from Carol, so it’s not impossible: here he blinked a lot – interpreted by some as him having been broken down by torture, and by others as Morse – while Rick tapped Lucille on the ground. But what did they say?

Redditor AMALLAMAAMA has been quoted by most as having correctly deciphered Daryl’s code: apparently he’s saying ‘I East’ – or giving some kind of indication that he’s east of an important landmark like The Hilltop or Alexandria. Rick appears to register it, but so far hasn’t spoken to any other characters about it. Instead, maintaining that Negan is in charge and they must surrender to his wishes. Reckon the theory’s right?
