A recent trailer of The Walking Dead: Daryl Dixon could be hinting at Laurent being the first immune character, which changes the future of The Walking Dead franchise. The upcoming Daryl Dixon spinoff reveals that Daryl is in France, but he has no recollection of how he ended up there after being washed ashore. Rescued by a religious community, he meets various new characters who task him with a mission to deliver a kid, Laurent, to a specific location. This mission will almost certainly provide insight into Laurent's story and whether he's the key to a cure.
