Monster Babies
Anyone remember Capn_Mactastic? Awesomesauce, pure awesomesauce. But anyways, I went back and re-read "Bad Day at the Lab", which you can find here. In it lizard!Mohinder, ya know after the rejected serum injection, jumps Sylar and has nasty gooey sex with him. This is when Sylar is still Noah's partner at the company. Weeelllll, the company comes to the rescue and Noah sees an opportunity to tease.
He says, and I quote, "Well, as I was saying, we don't know what effect that serum has had on the doctor's reproductive system. It's a good job you two didn't get up to anything, otherwise you could have little mutant sperm digging through your insides looking for somewhere to hole up and make monster babies.”
Then Sylar threw up.
I drew fanart for here, depicting what I think went through Sylar's mind at that point. It can be found here.
