Here is how it goes. When we see them first meet they clearly have a history. It's one were they don't like each other. A curious thing to think about though is that Guinan recognizes him while looking like John Delancie. Why would he look like that when meeting Guinan in the past when he can take so many shapes?
My idea is that is what Q use to look like even before the Q evolved and the Q are actually the Al-Aurans in the future after that evoultion. We already know they live a long life so it makes sense that they could grow and become more powerful.
We also know Guinan has a son who she said never listened. What if they had a feud that lasted all the way even when their species evolved. Q can travel back in time and meet his mom before she evolved herself but Guinan knows it's her son because of her ability to sense things or maybe just told her. Maybe this is one of the reason's why Q seems fascinated by Picard. It's because his mom was as well and he wanted to know why she felt that way or even mess with her via by messing with Picard.
