Iva is with the Revos lol it's a pipe dream to have him teleport all the way here. I'm gonna stick to the assumption 106.101 made about the girl being Black Maria for now (The hearts at the end of the sentences and the music note in the speech bubble implies she's signing like Maria does).
Now as to who the other person is well idk. The laugh was a good queue but the current translations seem to point to it being the girl's laugh so it could be Who's Who or even King if Oda really wants to go wild
