oh, another point on this song, very important: The husband walks in, Kills boyfirend, they realize Tommy had seen it and say "you didn't hear it, you didn't see it..." etc. if you notice on the album, the lyrics are echoed, this is Tommy seeing the murder through the mirror, and because of the trauma, the mirror is his gateway into being the deaf, dumb and blind boy as the shattering of the mirror will be his awakening out of that state later.
