I've said this so many times before. If I know that Q is going to be in a Star Trek episode, I feel like running. What's the point of doing anything when he has the ability to change anything, do anything, and mess up any sort of logical progression. Once again he sticks his nose in Federation business. Why this is, I don't know. He has control over the universe. Why mess around with mere mortals. As for Vash, I found her tiresome and uninteresting in TNG, and, once again, she is tiresome and uninteresting. Please don't have either of them return.
