Yup, kind 1.
Along with the content of the reply, the event includes your pubkey and a few other pieces of info (what note ID you're replying to, which relays to send to, proof you signed the note with your private key, etc).
This is what your note looks like. It's a little busy, but "p" means pubkey, and "e" means event ID:
