Discord (dusting himself off): you know Twilight, just because I'm immortal and impossible to physically injure doesn't mean you can just nuke me whenever I annoy you.

Twilight: Aww come on, it's so much fun, besides, you're the only thing I can test my strongest combat spells on. Can't risk actually breaking something or hurting somepony.

D: Yeah, but it's still a pain to clean all the soot and ash out of my fur.

T: Just look at it this way, you're doing me a favor by helping me learn to use and control my alicorn magic. Good friends do each other favors and in return I'll owe you one. Also don't you like the chaos all this unrestrained energy unleashes?

D: Fine, but give me a little warn-(explodes again) Okay now you're just messing with me. I really should have suspected something when you asked me to take you to a comic strip without a background.
