Donatello was happily chatting to his online friend. They had met through a game and he always enjoyed chatting with them.

But the thing is. He NEVER once told them about being a Mutant. Which means, the person on the other side definitely thought Donatello is a human.. Which is why he's always awkward and changes the subject about sending pictures, Video Chatting, and most of all meeting up in person.

"Ehehe.. sorry I have to go.."

He spoke nervously on a call as they wanted to Video Chat.
