Season 5 coming up

I've started to watch the previous seasons on YouTube to catch up before S5 starts next year. It's a real muddle with episodes given the wrong title and I have missed some and up in the air with some of the stories.

What happened to Lucy's engagement to the school teacher? I thought her decision to follow Justin again was a bad one. I take it it doesn't last?

Is there a site which gives you the blow by blow of what's in each episode?

I'm looking forward to the next season.
