That's okay, apparently, a 4-panel manga was included with certain DVDs (the second vols I guess?). I hadn't noticed them much before either, but they're kinda... weird. ^^;; Will see about scanlating the two I did manage to scan later.
Otherwise, I've also scanned and did a quick (and unedited...) scanlation of the Victorian Rose Tailor mini-manga that was in the Jan issue of Cobalt. It's a cute one-scene involving Sherlock and Chris. :P
