The Star represents peace, harmony and tranquility. Possibly it is the calm following the storm that destroyed the Tower.

In this card, the storm has passed and the air smells fresh. It is time for renewal, feelings of hope abound. It is time to stretch ourselves, to look forward to new horizons.

Times change, as do we. A new day brings new hope.

When the Star appears in a Tarot spread it represents new possibilities, new hope, new opportunities. If well aspected then those opportunities will be recognised and grasped.

If badly aspected it can indicate a failure to recognise those opportunities, or lack of courage to take advantage of them.

The future starts now.

I just thought that Mary embodied so much of the Star for the boys - if things were just a little different then the boys would have much different lives. Her memory keeps them on the path their on along with the knowledge that there is so much more that she wanted for them and if she had lived they would have it.

When they see their mother again, it is in the house that they grew up in. Sam and Dean aren't sure if they should believe that the apparition that they saw is their mother or not, but they are hopeful that it was and that she has gone on to somewhere better. She left them a second time, this time she was defending her boys.

Every time Mary has appeared it has helped to strengthen the resolve of her boys. While it may be dark, she is their light that leads them on.
