TIME TRAVEL SPELLS

[vandergraafk]

In Chris-Crossed, Bianca and Chris use a spell found in the Book of Shadows that allows for one-way time travel. How this spell came to be in the Book of Shadows is beyond me? Worse: Wyatt is able to somehow modify the spell in order to allow for two-way travel. That makes time travel really a pedestrian feat. Hardly what I would expect for something so risky in terms of the proper order of things. In the event, here's the spell:

Hear these words, hear the rhyme
Heed the hope within my mind
Send me back to where I'll find
What I wish in place and time.

Whenever a Halliwell, Warren witch to be exact, needs a specific spell it "magically" appears in the Book of Shadows. If the Book alters itself to fit the sisters' needs, why not their offspring? It's one of the contrivances of Charmed that is particularly annoying.
