Nope.
Cast members said they don't know who it is? You actually believe them? LOL. Gullible kids.
Another MAJOR hint is with the POV shot of them in the truck with the lights (the episode starts with this POV shot looking at some crystalized light form). Clearly whoever, that is, is the one that dies at the end. They're not gonna show 2 POV angles from 2 different people throughout the episode. This wouldn't make sense. Walking Dead producers does these POV angles with a purpose and towards the end of the episode when Dwight lets them out of the van, it's revealed that the person who's POV that is has one or 2 other people in front of him. You can tell that there are other heads and people in front of em (you can see the top of someones head on the lower left corner). That tells me that the person who's gonna die is most likely the 2nd or 3rd person to come out of the trailer. This eliminates Maggie, Carl, Aaron, Michonne, Rick, Eugene, Sasha, and Abraham, right off the bat since they weren't in the van. That leaves Daryl, Glenn, and Rosita and nobody gives 2 shts about Rosita. Daryl was the first one out of the truck and from the POV shot it can't be Daryl since there was no one else in front of him. Leaving one person...
Not my fault you guys aren't smart enough to spot these obvious signs.
