DnD Central / Grammatical Mutterings
It's simply a neuter indeterminate pronoun. A construction like "The girl went shopping. It came home with a new hat."* is quite ordinary. "She came home…" would be ungrammatical in this context.You are most probably right, and I must be fairly outdated in German grammar. I didn't know about such usages of "es". For me, "Es regnet" was the most representative usage of it. Thanks, anyway.
