It was a massacre. Damon has not been back to that area, because he knows that he'd still smell the blood if he did. It's not the kind that can be washed from the pavement, washed away from the walls or the streets, because it was everywhere.

Everything that he needs is is in Josef's office so he hasn't had any need to head that way again. It's not like he needs any help to increase his blood lust lately. The feeling of it increases all on its own without the smell of blood.

There's plenty of places to smell blood in a city like Chicago.

Damon steps through the door. He even knocks for a change, because he is trying to be on his best behavior. Jeremy lets him in and tells him that Elena is downstairs in her room when Damon asks, and it looks for a moment like Jeremy is going to say more but then he seems to think better of it and doesn't.

What could he say anyway?

I saw that place afterward. I'm sorry.

Damon wouldn't want to hear it, and he already heard from Elena what he'd done to her. Not that he's not grateful that Elena was kept far, far from that street. It's just further proof that Damon is extra... Damon, extra dangerous, and Jeremy won't be looking to get his neck snapped again anytime soon.

Even if he does come back from it.

Damon expected accusation or anger so he is... slightly surprised when he hears neither. "Returning your necklace," he answers, holding it out to her by the chain.
