What do you think that "we did it, we really did it" means
So. many. possibilities.
So, most of us think it revolves around three different scenarios:
They had sex
They joined together to finish Ezra’s book (look at details in my spoilers if you don’t know what I mean)
Or they got married
Now, this quote was from Marlene. Typically she only gives spoilers from her episodes. She only wrote 620 (the finale). So, sex? Crossing that off. I still think they’ll hook up, but that won’t revolve around the quote.
That leaves the book or they get married. I’m leaning more towards them finishing a book together, because it’s so hard for me to imagine the writers giving us something as amazing as them getting married. But it’s still a thought that’s in my head.
It still could be something completely different, those are just my theories. What about you guys?
