[spoilers] Harry and Ruth

[Beatriz]

I partly agree with both of you, HellsBells and Moonlight. Ruth wouldn't have broken her commitment to George and Nico in the first place. But the thing is that George and Nico would have wanted to come back home, but Ruth's coverup was blown so she wouldn't be safe there.
She would like to live a normal and calm life, but deep inside her, methinks, she loves her job.
Harry's love has caused her a lot of pain but that was because she had to leave and she was very insecure about it. But she had evolved in Cyprus, and there would have been no hurdle in their way.
And as it was said before, Harry is Ruth's true love.

*EDIT* I hadn't read Tea Lady's post before starting to write I completely agree with her.
