Glenn had recently gone on a supply run with Tara, Eugene, Noah, Aiden and Nicholas, the last two being from Alexandria, which you all had just recently been made a part of.
Glenn had come back, bloodied, silent, crying and with two less people. Noah and Aiden were gone. Glenn hadn’t answered anyone’s questions, just sat on the porch of the house the most of you shared, with his back to one of the supports.
It was hours before anyone got him to talk, and it was you and Rick. Apparently, Aiden had been trying to save the group from a roamer, which had a grenade that he hit with a bullet. It caused Tara to slam her head against a metal plate and start bleeding, and caused Aiden to get impaled. While Nicholas tried to run, Glenn and Noah risked their lives to save him, and Noah ended up getting ripped apart before Glenn’s eyes.
