Lyric discussion by PersusNine 

The song is clearly about a love triangle but I've often wondered if the master and the prisoner are actually the same person. It could be interpretated as being about the singers personality changing so he doesn't always identify with himself. Perhaps in a manic depressive way since there is such an obvious contrast between the two personas. The Master is wild, free but also destructive and in some ways broken while the prisoner is quiet, thoughtful, used to loneliness, sick but also in the end the one the lover actually cares about.

If they are same person then when the Prisoner persona says that the Master persona told the lover everything he keeps locked away in his head which would could be taken quite literally as the Master telling all the Lover his secrets which the Prisoner then regrets.
