Asshole
Because obviously pretending to be someone that we knew and lost was going to win you friends here. You could've picked some other guy that's in some other story. I don't give a shit. Doesn't matter now anyways. Point is, he's already lost his Sherlock twice, watched him die twice. Now he finds out that you aren't him, so he's losing him all over again. He's been through enough. Hurt him again, and we're REALLY going to have a problem.
