I thought I had misunderstood that part and I was still in doubt - but the story at the beach house with Red & Katarina was just a fake story (there was a whole episode of how Katarina went swimming and disappeared)?

I remember this episode, maybe it was just a dream or a metaphor on the disappearance of Katarina...

I hope there will be a season 9 so we'll know who Reddington really is (especially with his fire burn scars on his back) and who he was to Elizabeth since she couldn't read her Mom's letter.

I guess you didn't understand that Reddington is Liz's mother Katarina!
