And yet more setlock.

Yes, I cheated; I actually posted this safelock pic instead of linking.  It is the mildest setlock/safelock you'll see.  Damned cute -- Ben in costume, posing!

Safelock:  Martin and Ben in costume, grinning infectiously.  Rupert Graves!

That grin.

Definitely setlock, involves costumes and our lads.  A funnier version of Ben and Martin, same costumes; Tweeted here.  For more, here is chantokita's setlock tag.  Twelve-hour (!) night shoot photoset on amygloriouspond's tumblr; Tweeted here.

Bonus:  That Guy!  The one we won't ever (?) see again.  Supposedly.
