[He wants to snarl at the man to get out of the aquarium and never darken his doorstep again. But John's a practical man. If Sylar has killed Sherlock, he wants to be able to get at him and hold him and... possibly murder him in return. At least John is seriously considering it, even if that wouldn't be the right thing to do. It would be the satisfying thing.]

Stay where you are in the aquarium. I'll deal with you when I get there.
