Code Geass: Lelouch of the Rebellion II - Transgression

I've seen code Geass season 1 so I understood the first movie and half of this one but the second half was incredibly confusing 16 episodes of season 2 which I haven't seen as it's hard to find in the UK condensed into like 60 minutes I barely got even a semblance of plot and I feel like if I ever do watch season 2 Ive ruined it for myself. I would highly recommend you watch season 2 before this learn from my mistake, here's hoping chapter 3 makes more sense with it being 9 episodes in 140 minutes. But from what plot I did get I can imagine the first 5 ok r so episodes of season 2 are bad so I may not be missing much.
