I have indeed raided spooky_doings' vaults, and it is absolutely horrifying that there is such a lack of Spooks fanfiction. I'm not even talking about the quality, the quantity in comparison to some of the other rare-fandoms out there is just criminal. And I admit right now that I am more of Tom-fan than any other of the characters, though I promised myself that I'll give Adam a chance once I get season 3 in my hands. I'm just surprised that there haven't been more fics out there about re-introducing Tom back into the MI-5 folds (I 'Groundbait' is the only one I have encountered that have attempted to write Tom back into the story).
Re: More Tom, because you are like the only one who's listening.
Overall, there just needs to be more Tom.
