We haven't seen that look in a while, specifically 60 pages ago, on strip 178 (well, technically 2 pages ago, and then 58 pages before that, but sixty sounds better :P). But no matter how long ago it was, Daryil's particular look is just as scary now as it was back then. Add that appearance to a pose that looks as if he's about to bad touch Keaton, and you have a hell-a-scary panel. >:3
I wonder how long before someone gets the reference of the tagline.
I don't know if he looks scary to me. It looks more to me that looks sorry, sad, then finally sadly resigned to what he has to do.
Though it does look like Keaton on impulse did something she actually regretted later. She actually looked stunned after she took that wrench to the back of that guys head.
I feel sorry for her after this point. After all the generosity they've given her despite her previous actions, she messes up... Maybe they're be nice enough to keep her body alive and preserved though? Second or third chances are tough to come by some times.
