Daryl has to escape at some point, he won't always stay a prisoner at the Sanctuary. And I think he'll end up at the Kingdom. Here is how and why.
Daryl & シェリー, シェリー酒 ~ 7x03 ~ The Cell
I think in the end, Dwight and シェリー, シェリー酒 will help Daryl escape. He can't escape alone, that's pretty much impossible, he needs help. At least from Sherry, but I'd like to think Dwight will be in on it too.
Dwight ~ 7x04 ~ Service
After he does escape, he can't go back ホーム to Alexandria. That's the first place Negan will go looking for him, and Daryl would put everyone at Alexandria in danger for going back...
