SUMMARY:
After reconciling with Ross and starting their relationship, Rachel makes a painful discovery concerning Ross when she finds a paper with a list comparing her and Julie. Monica gets an impossible task at her new job to make food with a disgusting chocolate substitute called "Mockolate."

I always find this so annoying, they spend a lot of episodes with Ross trying be with Rachel and when they are finally together they broke up in 30 seconds...

I like it. :(
I like it how, at first, you understand why Ross did the list and you are happy that the list of Julie says "She's not Rachel". But then when Rachel see the list, you feel bad for her and again, you understand why it was such a bad thing.
And I do love the whole thing that actually makes them be together: that prom tape. It was the first time Rachel saw how much Ross cared for her, so all that "list thing" became completely forgetable.

I like that this episode is real and not just happily ever after like you'd expect people to be when they get together but man, I wish it didn't happen as quickly as it did. The audience was just getting excited with all the Ross and Rachel build-up then when it finally happens, it crashes all down. But I do like the way they reconciled in the prom video episode.
