[The clip opens with a sideways close up of Bruce's face. He has not been painted yet, but that isn't the issue. It's nighttime, at least according to the clocks. He gives a squeak when he notices the communicator is on and starts fidgeting with it. What exactly he's trying to do isn't clear until he turns it so that it's obvious that it's sitting on a night table. Said night table is next to Sora's bed and viewers are now treated to a sideways image of a snoozing Keybearer.
Sora's not quite sleeping peacefully, however. He's fidgeting at least and occasionally mumbles something in his sleep. Whatever he's dreaming of, it might not be pleasant. Jelly Bean is sitting next to him on the bed, whimpering and occasionally pawing at him. This doesn't last long, as Sora wakes with a start, sitting up quickly and sending the Meow Wow tumbling off the bed. Whatever he was dreaming about, it seems to have involved combat, as he has his Keyblade in hand and the beginnings of a Thunder spell crackling in the air around him before his sleepy mind realizes where he is.
He sits for a moment, panting and clearly trying to wrap his brain around what's going on. After a minute, he settles down, dismissing his Keyblade and muttering one word just barely loud enough for the communicator to pick up. He doesn't sound puzzled or confused, though. He sounds more like he thinks he should have thought of this sooner.]
... A Keyhole.
[Jelly Bean hops back up on the bed, sits down where he was before and gives Sora a Look. It is the kind of Look one might expect on a disgruntled pet with a knucklehead master who has just inadvertently kicked him out of bed. Sora does not notice this Look right away, being too busy thinking over what he'd just dreamed. Jelly Bean barks. It's the kind of growly, irritated bark that perfectly compliments the Look. Sora reaches out to absently pat the disgruntled Dream Eater on the head.]
[He turns to Bruce, as if intending to ask him something. Whatever he's going to say, it's forgotten when he sees that the communicator is on. Sighing, he picks it up.]
[Well this is awkward. How long was it recording? Sora looks to Bruce, who squeaks at him from off camera. The bat sounds cranky. Had he also gotten kicked off the bed at some point? Sora looks back at the communicator and seems to debate something for a moment before he speaks up. No, he doesn't actually want to talk about this right now, but he doesn't realize he was recorded thinking out loud about the Keyhole. He'll find out the hard way when the replies start coming in...]
So apparently our Spirits can turn the communicators on if they mess with them enough.
