#2. What are they planning to do with the explosives?
Fat Joey, Negan, and The Saviors were talking about how The Sanctuary was using a system of explosives to keep walkers away from their home. One example of that tactic was seen last week when a cable with explosives attached was spotted.
Thanks to some surprising bomb defusing skills from Rosita, the group now has a large amount of explosives at their disposal. But the question is what they will use these explosives for now that they have them.
The most obvious thought is that it can be used against either a large group of The Saviors or to stop some of their vehicles from doing damage or bringing more soldiers to the fight. Either way, it will be a huge asset to the group.
Since some of the explosives did go off and many of the walkers were killed using the cable, hopefully The Saviors won’t become curious of what happened to the rest of the dynamite and Alexandria can surprise their foes with it.
