Polly is the only one that Thomas will confide in. When she is eventually able to wheedle the information out of him, she tells him to dump the guns before he gets hanged for having them.
Polly finds out that Ada is pregnant with the child of Freddie Thorne, who has since fled the city from Inspector Chester Campbell. Polly tells Ada about how she was 16 when she first became pregnant and how she almost died from the abortion, hoping that the father of her child would come back. She tells Ada that they should take the train the following day, for Ada to get a proper abortion.
The next day at the train station, Freddie arrives as they are about to board the train.

She is not surprised when he cons his son, Arthur, out of five hundred pounds.
