Going with Alden.
SPOILERS BELOW IF YOU HAVEN'T READ THE COMICS
Everyone keeps saying Gabriel and his comic death.
Here are characters that outlived their comic death: Carol, Ezekiel, Rosita, Luke, Kal, Moragn, Abraham, Tobin, and Scott. And I'm sure I'm missing others.
The point don't always assume the show will always follow the comics.
Also for those comic readers you already know TV Gabriel and Comic Gabriel are not the same. Sure they started out the same but TV Gabriel is much more brave and stronger of a person and there's no way he is going to run in fear of The Whisperers.
Only possible way is if he's running to save the children and then he falls...
