Wait, so, you were planning to help, and you don't want to see Sherlock get hurt, and Joan asked you to help even though you were already planning to, but you were only going to help if we wanted you to and you got a vibe so you were going to not, but if we "still want your help" then you're still willing? Is this going to be one of those things where if someone pisses you off you're gonna refuse to help? Because this isn't some pissing contest, man, there's lives at stake here.
