They just set up the big finale and then stopped right before it! You’d think even if they wanted to go for a cliffhanger, they’d let the battle progress more and stop when everyone had taken some major hits and were on the verge of losing. I thought maybe it was a budget issue but apparently Simon Barry said that when he took the script to Netflix, they were like, how about stopping it a little earlier? So maybe it’s an encouraging sign, where it’s kind of implicitly promising a second season already (unless the show does abysmally, which it doesn’t seem like it’s doing?).
Unless you meant the whole final reveal, in which case, never trust a fictional angel. 😛
