Bah, it’s ok. I was a lil rude in my reply too. We all make mistakes!

The word “obviously” was a gross exaggeration which I regret. In the previous sentence, I’d said “seems like… to me”, so I’d thought it was clear I was speaking from opinion rather than stating what I thought was a fact. (Certainly if it were “obvious” the picture would already have been tagged with grimdark.)
 
I did a poor job of expressing myself, for which I apologize. Please note that I wasn’t trying to argue that the image should be tagged with grimdark or semi-grimdark. I just said it felt that way to me, primarily because Twilight looks sad rather than frustrated or bored. In my headspace, if Twi had just saved Pinkie’s life, she wouldn’t look sad like this. The picture makes the most sense to me if Pinkie is dead. (This is not something I want: Pinkie equals best poni.)
 
Once again, my words were intended to refer only to my perception of the picture. I am sorry for voicing my opinion poorly.

@TricksterWolf  
Yet you said that this cartoon horse is “obviously dead”

@Blissey1  
Only because it’s a cartoon. In real life somepony sealed in ice would be extremely dead.

@TricksterWolf  
Just like you can’t tell that she’s “obviously dead”

@Meanlucario  
You can’t tell that from the picture.

@TricksterWolf  
No, they just froze Ponk until she cooled down enough so her unbounded energy won’t destroy Equestria.

Seems like grimdark to me. Twi is frowning and Pinkie’s obviously dead.

@Einsman  
Ask him on Tumbler.

insert worn-out ‘firefox has frozen’ joke

What part of Canada?

Remember, this is Pre-Alicorn Twi.
 
It’s okay, just be more observant in the future, alright?

Heh, Twilight froze another one of her friends in the past.  

@Twi_Clown  
Because it’s funnier this way.

@Twi_Clown  
Its Pinkie Pie, best not to question it.

Have you been through Ontario, the province I’m living in?  
Because you bet yer ass it’s cold over here!

@EmployeeAMillion  
If she could defy the laws of physic why is she frozen?

I thought this was a reference of some news that came recently of someone that found a frozen fox…
