We All Did [Thor]

Loki is dead. Loki took his own life rather than face his family for another moment, and Thor doesn't understand why. Odin and Frigga do understand, however, and even if they're too late to spare one son with the truth, they can do that much for the child they have left. At long last, they tell Thor the truth about Loki, and it's a truth Thor has to grapple with alone.

"Did you mourn?"
"We all did."

Post-"Thor". One-shot. Characters all belong to Marvel. Based on a one-shot I saw on FanFaction. I lost the original thing, though, so I'm honestly not sure how much of this is original and how much is from that.
