Yeah, I just saw that and sent a post comment mentioning that I don't recall exactly why I thought it was slow. Like I said, it's been a few months since I watched those episodes.
That's something i love about it, so many shows have a habit of ignoring their plotholes or pointless storylines but this show has a habit of calling back to them much later with an explanation. It's pretty cheesy but Elliot while narrating often says something along the lines of "are you paying attention to me?", which i think is a hint that what he says isn't random pretentious nonsense but stuff that will be relevant later. It plays with the whole Lost puzzle concept, except the writers have properly thought it out so they don't end up in the holes the Lost writers did: they admitted they were making it up as they went along. And you also have to remember that we as the viewer are Eliotts subconscious, he is always entirely truthful to us at least as far as he's aware because he thinks he's talking to himself. This isn't a spoiler or a 'most characters who narate are doing this' thing, it's a specific thing introduced from the start that i don't think most people pick up on. Mostly because you are used to the narrator in movies or tv shows not being the character you are watching or being a future version of themselves talking about their past.
