Just call him Sly the Slayer.

On Monday's all-new Scorpion, Sylvester (Ari Stidham) finds himself heading to prison with a serious neck tattoo that would intimidate, well, nobody. But woe to them because he's a psychopathic serial killer with a crazy rap sheet.

That's his cover story anyway. Sylvester is forced to don that unflattering orange jumpsuit to go undercover in a federal prison to obtain information that will save the lives of three judges. Check out the exclusive clip above to see how he gets into character. Cabe (Robert Patrick) may need to drill him a bit more on prison lingo. Let's hope Sylvester finds a fellow Super Fun Guy aficionado in the clink who can protect him!

Scorpion airs Mondays at 9/8c on CBS.
