Okay, I think he's talking about King Of The Clouds on this whole video and if he is, here's the thing.
Brendon says that the whole time he was talking to Jake, Jake was writing what he was saying while Brendon has high. King Of The Clouds has some deep lyrics, if Brendon was high while talking to Jake, that means Brendon could talk about deep stuff while he's high. You know what I'm trying to say? I'm not even sure what I'm trying to say but basically King Of The Clouds might be a high song where Brendon was talking about something maybe about Ryan, seeing that he said "sun" in the song, while he was high and Jake wouldn't know that much about it because Jake doesn't care about that kind of thing's so he just wrote his words down while Brendon was talking about something deep while he was high.
I don't know, it's 2 AM and I just the interview and thought about it.
