Shadow knew he was weird.

(YOUR SONIC) *Being created as the Highest Life Form by human standards meant not having the basic skills of the Mobinian culture he belonged to, knowing only rough indications from books and hearsay. The scientists of the Space Colony had never seen him in a spectrum other than weapons, so the black and red hedgehog had never been interested in the intimate part of the relationship between the Mobinians, whatever the form of this relationship might be.

So he definitely didnt think he'd end up pregnant if anything. Apparently form just being around Sonic he had basically "absorbed" his DNA from any little touch and had perduced a baby?! Now he was one month pregnant and his belly was showing although he didnt tell anyone intill he took a test.

He goes to Sonicbone late afternoon. It was a odd thing going to his rivials house, let alone to tell him that they basically made a baby.

He knocks on the door a normal stoic grumpy expression on his face. He outs a hand over his stomach trying to hide it. How on earth would he explain that his alien body did this?

Shadow: "awnser your door dumbass" He said gruffly with a small growl.
