SIAMÉS - "The Wolf"

The wolves are the  representation of death.
"EVERY NIGHT AGAIN DANCING WITH THE MOONLIGHT SOMEWHERE FAR AWAY I CAN HEAR YOUR CALL…"

This is because death is not too old or too young, it's forever, present every day and night, hiding awaiting the right moment.

"NOT TOO CLOSE, NOT TOO FAR"

"EACH AND EVERY DAY HIDING FROM THE SUNSHINE WANDERING IN THE SHADE NOT TOO OLD, NOT TOO YOUNG"

and

Once you do your last step it comes out and materialise for you.

"AWAITING YOUR MISTAKE"

And she/he's ever present, you can't feel it but she/he's there.

Simply put, the death is awaiting and once you do your last mistake will comes out and once she/he materialise, you are screwed. The thing that made me think that is the lyric part that says: "CAUSE YOU CAN RUN BUT YOU CAN’T HIDE I’M GONNA MAKE YOU MINE" And she/he know that you are at your last step, because once you pass it, you will forever keep doing this last step, so it's time to purify your soul, taking you away.

"CAUSE I CAN FEEL HOW YOUR FLESH NOW IS CRYING OUT FOR MORE…"

Now, observing the 3 people:
1) The BAR guy last step was drinking. The wolves materialise. It's time to be taken
2) The girl last step was smoking once more. The wolves materialise. It's time to be taken.
3) About the motor guy, we don't know his last step, but what is clear is that he's running by a lot of time and death became stronger and grown up, this mean more wolves because he's delaying the inevitable and so he must be taken quickly. But in the end, he saved both the Bar guy and the Girl, so the death stopped chasing, observing this act of courage awaiting for him to make a decision. Now, once the motor guy take the decision to fight head on, the death decided to fight him one on one, that explain why only one wolf came out of the pack.
