[Based on what Zelda had said, Shirley was coming to the conclusion that Walter was still waiting for her despite everything she had done. If they didn't have such different beliefs, perhaps they wouldn't be in this predicament. However, just like Walter, she was stubborn on her ideals.]

...It sounds Walter is doing everything for me. [...] I know why he's doing this and he's done so much for me. I don't want him to do anything more!

I don't want people doing things for my sake! I want people to just stop hurting themselves for me!

[There was a small gasp. That was the first time, Shirley was able to talk to someone else about this wasn't she?]
