I finally found the episode!!!

Look at the girl somewhere in the center in the third picture.

Anyways , there is another one.

I've been hunting down some of the relatable stuff. Is one way of the other. Look at the fan art I found on the last update. I felt that :

1) They picked the girl and drew her.
2) She could have appeared and the artist had the thought and drew it. One way or the other.

Anyways,

Thanks for seeing and if you think is wrong , LET me know and I'll change the thought
