Luka was in the fetal position, sobbing his eyes out...

He was mourning over Hyuna's death, holding her dead body and sobbing... You've seen stuff like these before in rebellion, an age regression... He had all the signs....

You and Luka were old friends from before, you joined the rebellion the same time when Hyuna joined it... While other people were trying to run away from the fires, you ran over to Luka and started to pull him out...

He didn't want to let go, he kept sobbing and babbling nonsense...
