Ethan's English Autocorrect

I overheard Ethan and Ayane having this conversation earlier

Ayane: Ethan, where's the paper?   (they were drawing something)
Ethan: It's on the table where the computer was.

He looked to the direction of the table, saw that the computer is still there, realised he used the wrong English word, and quickly corrected himself.

Ethan: It's on the table where the computer is. Is in. Is in on? Is on!

Just like a computer, he auto-corrects himself. Nice!
