Lost Angel 4

I almost forgot about this... Wow it's like the book wants me to complete it; I randomly open it, and it's on chapter 31 !
Anyway, this time, I'm blogging till Chapter 41!!! Here goes nothing :P

• Gertie's idea is opening a plant nursery. She promises to employ Doug, Ellen, and Percy
• Maureen still can't see them as her family
• Doug told Ellen about Gertie and Maureen and Ellen's new friend, Janet, pointed out to her that though they are different, they're still good people
• Hilda and Doug finally fill the gap between them and begin to get along again
• Gertie found a buyer and location for her plan; Billy came for a weekend visit and Ellen's feelings were rekindled
• Gertie gave Hilda an angel-shaped ornament, which Hilda's mother had loved and gave Ellen a new coat for her 16th bday. 
• Hilda, seeing her daughter so beautiful in the coat, finally began to acknowledge that she was becoming a young lady, but then Hilda immediately told herself that Ellen was still a long way away from meeting boys
• Hilda seems very picky about who she wants Ellen to marry; she doesn't approve of either billy or Percy
• Ellen, Janet, Percy, and Billy all go to the dance. on the walk home, Billy tricks Ellen; after Billy leaves, Ellen tries to act normally, but her inner turmoil constantly haunts her. she tells only Janet, who comforts her
• Billy marries Sheila, since Sheila is pregnant; and with this in mind, Ellen realizes she's pregnant too.  Though her there's something obviously wrong with her daughter, Hilda avoids a confrontation with Ellen, thinking if she said less, Ellen would get over what was troubling her.
• Ellen told her parents what happened, and they decided to take Gertie's job offer because it would help Ellen. When Mabel and her family found out about Ellen and Billy, Percy offered to marry Ellen on the condition that Billy never knew the child was his.
• After things had settled down, and Percy and Ellen, and Doug and Hilda moved in Surrey to work with Gertie.
• To Hilda, the move had taken them away from London's 'bad charm'; she also believed that the angel-statue was 'watching over' them.
• Ellen was relieved that she didn't have to become a burden on her parents as a single mother, but she still had two worries regarding her marriage: one, she was afraid that since her marriage had so far been platonic, Percy would cease to love her as much as he did; and two, she couldn't see how Percy would ever be able to be a father to her child
• Valerie, their neighbor, seemed to know about the spiritual issues Ellen had always wondered about and pursued. Val claimed that Ellen would have a girl and she would have a boy

Questions:

1. How does Hilda's faith transition from a non-believer, to believing in an angelic statue? What does each faith have in common?
2. Do you think Billy will be able to sense that the child is his? Will Percy be able to love the baby, though it's his brother's son?
