Time Travel in general gives me a headache.

Heroes seems to follow a fluid belief of time travel where you can prevent the past to change the future which means there has been a lot of time travelling and showing what may or may not happen.

Also we have sight seers so you have people trying to prevent fates they know by avoiding them but running smack into them. Would it have happened if they didn't know?

X-MEn which I'm sure Heroes took its cues from also suffers from a similar fate which is made even worse when you got parents hanging out with their future offsprings.
