A question about Tom

[Tea Lady]

Series series 3 and 9 Spoiler: show

I'm not sure that we know that Tom and Christine are married. I thought that was just fanfic life. I would guess from the reaction of Harry in meeting Malcolm again, that they had kept in touch which is not so surprising, especially as Malcolm was keeping tabs on the Albany list. I wouldn't be surprised if Tom left and had nothing to do with the Service again.
