If you notice in all three bios, the word “feelings” is used. Now, it was very easy for the audience to decipher that Bob and Sasha developed romantic feelings for each other.
So the same can and should be said for Daryl and Beth.
There is no indication that Daryl and Carol have developed romantic feelings for each other per AMC.
Furthermore, it can’t be said that Daryl and Beth only have a friendship because that would imply that the feelings that Bob and Sasha are developing is familial.
AMC strategically let these bios out weeks before the premier, so we have to take these bios into account going into season 5.
Which confirms that Daryl has feelings for Beth. x
