Maggie giving Negan a gun to help out against the walkers
@Mock did she die? umm no Maggie is a resourceful, skilled woman, Negan knows that, and if i were in Negan's position there i would've done the same, i mean you don't go saving someone who wants you dead
also The Reapers, they weren't in the comics, sooo they for the first time steered clear from those in this final season
from the extra episodes of season 10, we already know their leader is a man named ''Pope''
what we know more is they run Meridian now, formerly run by Maggie and her group and Pope has marked Maggie for death, so i think she has done something bad to him to deserve that death sentence

only my theory of course
