It took a season and a half, but Elementary finally tackled the topic of the mob this week.

When the son of a big-time former crook was brutally killed, Sherlock and Joan jumped into action. By getting dressed up and looking rather dapper, that is.

The tension between Sherlock and Marcus also came to a head, while we learned Watson can recognize a corpse with no head and no hands. She's got serious skills.

Elsewhere on Elementary Season 2 Episode 13, the winning scene definitely goes to Bell and Holmes, with the former even referring to the latter as a "friend." Did anyone see that coming?!?

Watch Elementary online now and see what else went down:
