Inb4 the changeling is in every single episode like this.  
Then the season finale is Chrysalis’ return, and they were all like “Oh why didn’t we see the signs” etc.

looks like it. Could be just a gag. But with DHX/Hasbro these days, you never know….

@Ping_chan  
Well one technically did in Episode 100. But I guess you mean with an actual speaking role in the episode

I would really like to see a changeling find a role in a episode and not be evil.  
Like, redemption, or something.

Well that’s an utterly random as hell cameo.

He just wants to meet his dad.

Hmmm I really hope that is a nice bit of Foreshadowing for the finale and not just some background gag.

I was wondering what that was…

Oh shit that is absolutely a changeling.

I was wondering what that was at the end. I saw something black flying in the air but thought it might’ve been shadowed out. So it was changeling…

Foreshadowing?
 
Is Chrysalis finally going get reformed killed?

Oh hello!

Oh dear lord if Chrissy does come back I hope it isn’t another “reform” the bad guy type deals.
 
She’s literally my favorite villain.
 
It’s probably just a funny cameo though I feel.

@Spirit  
ish being an extra three months.

@PonyPon  
what if the changeling was the kid!?!?!?! M.A. LARSON YOU MAGNIFICENT BASTARD! I READ YOUR BOOK!!!!

It was a good foreshadowing, but also obscure enough to keep us in the dark.

With all that love it’s like a mosquito drawn to a blood bank.

When one problem is resolved, we run into another!

saw the same thing on my tv, pixely but is defiantly a changling. fingers crossed for return of Chrysalis.

The Queen sent him to see what all the racket was about.
 
Hope they keep a close eye on the kid.

@Mori  
 
I knew it!

So… Chrysalis making a return?

I knew I saw something! At first I thought it was Luna though. Or maybe a hint about Sombra returning.

Where did HE come from?
 
Could this be a warning of the Changeling Queen’s return?
