What is driving Julia's fight for custody of Tommy? Is it out of love for him or Richard?
It's out of love for both of them. By the time Richard leaves Tommy with her at the end of Season 3, she definitely loves Harrow, but she's also starting to love this little kid. Julia's not the kind of person who likes to daydream and have expectations but I think by that point, the idea of them as a family unit has gotten the best of her. She also didn't know where Harrow was, so her "momma bear" instincts kicked in, given what she knew about Gillian. It's not just her growing love for Tommy - but understanding what his living situation was before. She's prepared to fight tooth and nail so that he doesn't have to grow up with that kind of person.
How confident is Julia in her ability to win the custody battle?
She has a trump card going into that courtroom—she knows what the kid went through and how he has nightmares about what happened. He looks to Julia for reassurance—not Gillian. But she loses that confidence when the judge points out that she and her father don't make a lot of money and she's unmarried. This is this first time it's like, "Shit." And now Gillian suddenly appears to have this wealthy suitor. When it was just her, it wasn't like she had the most stellar reputation in town.
Does she resent Gillian's weakness? Or can she empathize?
Gretchen and I were actually talking about that. Both of them are survivors who always readjust to their circumstances, but they have made very different choices about how to adapt. There's a part of Julia that's disgusted by Gillian but she also understands and feels sorry for her. She doesn't feel it's an excuse, but Julia feels really bad about the lot in life this woman has.
Has Julia forgiven Harrow for leaving?
I don't think she has. When Richard shows up, she's confused, hurt, sad - and there's definitely a part of her that's angry with him, too. The proposal comes more out of her need to save Tommy than "Let's get married!"
