The only times I've seen them were A) over at someone's house watching one of that season's recently-aired eps and being stuck seeing the associated Confidential because it's what everyone else was watching, and B) catching some snippets as I jumped through the "Gridlock" confidential looking for the kitten scene.

I might have to look for some of the Simms photo stills, though. But I suspect I'll refrain from speculating about why he didn't seem happy, because that way lies RPF. (And anyway I'm having far more fun fighting off the rabid plotbunny I got this weekend after having finally watching Blackpool -- I assume there's fic out there somewhere about DI Carlisle having a pocket watch somewhere that he's never thought to open, so I won't be tempted to write it myself?)
