The Walking Dead:10 Important Things To Remember Before Season 8
6. Heath Is Still Missing
Remember Heath? He went missing in episode six’s Swear, when he got separated from supply-run partner Tara. She was found and saved by Cyndie, held captive at Oceanside and narrowly escaped death (just an average day at the beach), but his fate remains a mystery.
We assume that Heath got clear of the bridge of sandy walkers, because Tara found a note left on the ground with the letters PPP written on it - another mystery to this loose end.
Unlike Tara, Heath did not find his way back home and, even on their return to Oceanside, when Tara brought Rick and company along to commandeer their guns, there was no suggestion of a rescue mission for one of Alexandria’s more spotlighted residents. (In fairness, Oceanside is surrounded by forest and there were more pressing matters.)
Showrunner Scott Gimple has said that Heath won’t be in season eight, but that could be smoke and mirrors because this is a plot hole too big to leave unanswered much longer.
