Issue in Episode 1 (still watching the rest of the show)

I'm now watching Original Sin after watching the original series & New Blood & so far I'm liking it. The actors they got to play the younger versions (specifically Debra, Batista & Masuka) are pretty damn good. However, In episode 1, we see Harry's point of view of the death of his son. This would be fine as a normal prequel show adding mythology to the history of the characters, but the framing device of this series is that Dexter is having his life flash before his eyes. This means you need to stick to scenes with him involved because he'd have no memory of someone else's memory. From what I gather reading synopsises, Harry's backstory is also looked in too, so I don't know if this is an oversight on the part of the writers or if they've explained their reasonings.

EDIT: I'm so glad they didn't neuter Masuka, he's still a vile pervert but now he's even more immature & showing the smoking in the office shows a nice subtle difference with society.

EDIT: Are people not understanding why I'm asking this? THE FRAMING DEVIXE of the show is that adult Dexter is dying & his life is flashing before his eyes. Your life flashing before your eyes does not include other people's storylines. This show isn't framed in the same way as the original one or New Blood where it's not solely focusing on Dexter's point of view. But the framing device being used is telling us he's either telling someone the story or he's thinking back to his past. He's talked in the past tenae several times already, showing that it's his point of view of the story we are watching. Sorry for those caps but I keep getting people asking me the same question like they aren't reading the full post so I feel the need to explain it since many seem to not understand what I mean. Perhaps the show was originally meant to just be a regular prequel, Young Dexter doing the voice over & they decided to add the framing device with Michael C Hall doing it & not thinking about how this affects the logic of other people's point of view.
