That is all. Everyone is overreacting "OH NOES, Pinkie Pie actually never broke the fourth wall!" But that is just wrong. Look at the ending of "Swarm Of The Century" or "Friendship Is Magic Part 2" or Pinkie Pie's cupcake song. She very clearly breaks the fourth wall.
There are many ways to break the fourth wall without ever looking at the fourth wall, so that actually changes nothing at all.
Pinkie Pie is obviously aware. If the animators are denying it, they're either lying or as was said earlier in the thread, she's genuinely a conscious entity as is manifesting into this reality.
People like to talk about her looking into the camera, manipulating the iris, etc. But there are things she does that are so subtle that I've only noticed them because I was freeze-framing through scenes taking screenshots.
I've mentioned this before, but for example:
That's during a roughly quarter-second zoom out, after Discord transports Twilight and himself back in time to show her his riddle. Pinkie is
looking right at them when they show up, even though they're faded to imply that they're invisible, and standing way behind everyone. Pinkie sees them,
blinks, and then looks forward to where everyone else is focusing on the present-time Discord talking.
She knew. And she didn't say a word.
It was an impulse reaction. Your eyes naturally track motion. She knew they appeared, so she looked. Then
realized she wasn't supposed to be looking at them so she played along.
Pinkie Pie is totally aware.
So next time Pinkie Pie smiles at you, smile back at her. Wish her well. She might just hear you.
