Let Jim pester Seb for a good half hour, take away all the weapons – get John to help – Sherlock will if it’ll annoy Jim. Seb will totally be on board to subdue Jim by that point. Just… srsly, when you let Jim go, shut them in a room alone. srsly.

*sigh*  Sherlock can’t seem to comprehend that all the weapons means all the weapons and not just the weapons they have.  Consulting 12 year old, indeed.  Making some progress in any case.  John and Seb seem to have bonded and are teaming up; that’s… faintly disturbing, actually.  (*giggles*  Oh, I’ll keep that last bit in mind, though… :D)
