But that’s whatThe Voiceis all about, right?

Well, we get a little of that in this fourth episode of Blind Auditions, too.

Kelly and Blake go head-to-head for two contestants here.

Kelly’s known for grabbing Spanish-language singers for her team, so it’s no surprise that she turns.

It is, however, a little surprising that Blake pushes his button at the last second.

Marcos joins Team Kelly.

The real battle, however, is for country/americana singer Mary Kate Connor.

Kelly takes the loss and later admits that it’s just the power of Blake on this show.

“Don’t tell him I said this, but he is, like,The Voice.

He’s, like, the king ofThe Voice.”

Kelly’s really going to miss her sparring partner once he’s gone.

“He will be missed by everyone,” she says.
