Wow..that was awsome!

Essentially a naturalistic depiction of the afterlife; lots more time but no externally-provided ultimate answer. The story’s “real world” seems to be a fishbowl with the angels outside. Is heaven another fishbowl?

Angels as agents with disposable memories. The whole concept of the guardians losing it; ‘quis custodiet ipsos custodes?’ Neat.

“This place can either be your Heaven or your Hell, depending on how you play this.” ^_^

The true love between fundamentally likeable, unfortunate people is good as always.

There’s relatively minimal character development and not much background on their relationship (then again, neither is necessarily so important in a short one-shot)
Maybe the psychological impact would be greater if there were a more immediate and/or more specific threat. Though maybe not everyone wants that.

Technical stuff that I noticed:

With respect to “So it is the weakness of Man after all” -- I don’t think Gabriel was ever human. Sorry to be anal. Unless he *is* supposed to be originally human in the story.

“she recalled the car speeding down the road, it hitting her”. The “it hitting her” sounds awkward to me given that ‘it’ is used in the same sentence as the antecedent. I’d change this, probably to ‘the car speeding down the road, hitting her’ or ‘speeding down the road and hitting her’. Or ‘..., the impact’ etc.

“a kitchen on the right, dirty and cluttered with dishes in the sink, and a bedroom on the right” -- a kitchen/bedroom on the *left*? Or is everything really on the right?
