Yeah, Fury [I think] radios that Clint's on his way to...uh, Loki [I think] and she snaps out of her daze and says that she's on it.

I think that whole scene's supposed to take place in like 20 minutes so she couldn't have been there too terribly long, but I think it's the one moment in the movie where she completely loses her shit so she's just kind of sitting there completely oblivious to the radio in her ear until Clint's name comes up.
