Anyways, it would anyways look completely suspicious to orochimaru for a war orphan to get a mutation for "cosmetic appearances" I think Jiraiya says it when he faces pain.

He didn't truly believe it until Nagato showed himself to be clearly about the rest during training. To orochimaru, the kid just had weird eyes like many other people. I don't see him abducting Kurenai because her eyes are suspiciously sharingan-like.

On the contrary, we've seen him abduct people who clearly displayed unusual ability. Sasuke wasn't interesting to him until he was a ninja already and showed his Sharingan.
