So occasionally he does notice. Or occasionally he decides to let it bother him. Frankly Cal doesn't see what was worse about that than anything Obadiah's said to Sherlock so far, but - okay, fine. At least it was something.

"We were watching a time travel movie," he non-explains; he's still addressing Tony, not Obadiah, and adds a look that says We'll tell you the real story later. It's not a subtle look, but one designed to let Obadiah know, silently but clearly, that he is not included.

Hopefully Tony will pick the more innocuous Milliways-related translation.
