Character death should ALWAYS be to further the plot. You handled this correctly. Actually, all actions taken should be to further the plot. Some storytellers can't be bothered to remember this and their comics end up dragging forever. Thanks for not forgetting this, and continuing to entertain us all these years.
Guys. We are officially closer to my prediction of the ending
It's gonna end in a giant orgy that last for 14 weeks. Milo's not really dead, so he's there too. And Dr. Redhead. Giant comic splash panels of every perversion imaginable for 14 weeks of updates. Charlie in a man-baby outfit.
FADE TO BLACK
Somewhere in that orgy, Jasper in a leopard print banana hammock. Mercer as Dr. Frankenfurter.
Guys. My theory is leading the way. How does this make you feel?
It happens to all of us. It sucks, and everything sucks. But when you do finally get out of the rut, you're gonna feel like a rockstar, double-gun wielding badass, ready to literally take on the world. Take your time, one day at a time, find little joys in things, and you'll get there soon enough.
