Covent Garden at 11.15 p.m. Torrents of heavy summer rain. Cab whistles blowing frantically in all directions. Pedestrians running for shelter into the market and under the portico of St. Paul's Church, where there are already several people, among them a lady and her daughter in evening dress.
The mother is talking to a bystander about the cabs while Freddy tries and find a cab company that has cabs available at that time. This is when we meet the Flower Girl after Freddy has bumped into her.
The Flower Girl: Nah then, Freddy: look wh' y' growin, deah.
Next day at 11 a.m. Higgin's laboratory in Wimpole Street.
Higgins: Well, I think that's the whole show.
Pickering: It's really amazing. I haven't taken half of it in, you know.
Higgins: What's your name?
In this scene the Flower Girl, as we now know her real name is Liza Doolittle, goes to Higgins laboratory. Liza wants Higgins to help her become a lady so she can work in the flower shop.
Pickering: won't you sit down?
Liza: Don't mind if I do
This is the scene where Mr. Higgins, Pickering, and Mrs. Pearce talk about Higgins teaching Liza how to become a lady. Mr. Higgins hands Liza a handkerchief to wipe away her tears after crying.
Pickering: He did. I think it must be regarded as her property, Mrs. Pearce
