A paradox is a space time event that shouldn't be allowed to exist without creating a sizable problem for everyone involved. Basically, it's when future events, through a broken, corrupted, or interrupted timeline end up impacting the past in a way they shouldn't be able to. They happen to me -- him -- us more than I'd like to admit. Especially when..well..
They happen. Don't worry though, that rule..doesn't seem to apply here -- which...really..I shouldn't say don't worry about at all because -- well, really, don't worry -- at least not yet.
