… I’m just going to ignore the comments so far and say something about the pic.
 
Siblings not having a fight ever is possible, because I really never had a fight with my brother, due to the fact that he’s 9 years older than me, and that he left to study abroad before I become a teenager. When I see him again, I’m already past that age of stupidity, so no argument after that point either.

Well, then I died and came back to life.
 
I also unleashed self-replicating Justin Bieber clones into your lab. Twily helped me create them.

@Randomosaur  
Ya.. you would be dead if you destroyed the anti-changeling shield generator, it’s powered by radioactive killer cobra-hornets!

Then it means, that her brother used a mind eraser spell to erase her mind.

@PwnyPony
 
No, you both are.

@Robomorons  
No, you are a child.

Or y’know they just got along well and Twilight exaggerates it a little bit because she loves him.

@Prof.NightJack
 
Well that’s mean.
 
Destroys the anti-changeling shield around your lab

@PwnyPony  
YOU’RE A CHILD!?

@Randomosaur  
For fun I guess.

@Randomosaur  
I am looking at these comments.

@Prof.NightJack
 
Why me?
 
Sticks a Spinosaurus tooth in your eye

That’s a French AIDS awareness poster, totally SFW.

@PaskaNaakka

I guess those are insex.
 
By the way, spiders and scorpions are arachnids, not insects.

@PaskaNaakka  
Pffffffffft….

@PaskaNaakka  
 
Dude, safe image.

@Randomosaur  
I’m beating Sid with a metal bat and you with a pipe wrench, so both!

@PaskaNaakka
 
GODDAMMIT, THERE COULD BE CHILDREN LOOKING AT THESE COMMENTS!

 
did it involve any heads getting bitten off?

@Prof.NightJack
 
Are you beating me or Sid?

Twilight doesn’t remember that time with memory erasure spell I see. Glad to see it’s still working.

@PwnyPony  
As one with a younger, if we didn’t go to school, fights would be hourly.
