I’m gonna guess other heroes dealing with whatever that is sent him away with a, “we don’t need you here!” or something. Context is important.

I'm thinking other heroes like Guy Gardner are fighting it. Unlike other iterations Superman isn't the only heroe in this world, let alone this city. Him sitting aroung and talking to Lois a bit before getting into action I think makes little difference considering you have other heroes out there.

I have a feeling it's a dream sequence or something cuz the place looks way too posh and rich looking to be Clark's apartment.

That’s how we’re going to be watching the official trailer while the drones start attacking us
