Grim, what would happen if you smiled?

The world would explode. The End.

Okay not really. In all seriousness, if he smiled people may just look at him weird, or be afraid. Most times if he smiles it means he's about to do something terrible. Like blow up the earth.

You should smile more often, Grim! Smiles are good for you!

But not the other people who live on Earth. X3

I agree. And I bet the earth isn't too happy about being blown up either.
Grim needs to live up to his name and stay grim, for the sake of others.

Woh.

You should see him when he's legitimately happy, it's rare, but amazing.

AU where Grim is always happy and makes rainbows and unicorns appear
That would be--

That's the AU where he is known as the Grin reaper. He must be quite the jolly fellow.

Lol that is hilarious. XD now i want to see all your character's reactions when he smiles XD

If one day I draw a bunch of my characters freaking out for no apparent reason, then now you will know why.

You should smile more often, Grim! :D Smiles are good for you!

But not the other people who live on Earth. X3

Oh yes, he could probably pull of a real nice smile if he wanted to.

It's a good thing we all live on cs then 8D

Oh my goodness, the poor Moon uAu

Don't worry, i'm sure it'll be fine...
