Two questions about 4.1 and 4.2

[JHyde]

I don't think Tom was ever informed as the attitude is (at least at this point in the series) that Tom never had contact again with anyone he worked with. I always wonder if he looked at a paper during the whole Agent X shebang and wondered if it was someone he knew.

As to Danny, Tom might have known if he read obituaries in the paper, as surely his death was announced (albeit with a fake job, if one was mentioned at all).

As to the guns question. There was a real shift in the show with regards to firearms between seasons 3 and 4 as well as in the missions officers were sent out on. To be fair, pulling a gun on your colleague (I Spy Apocalypse) is very different from pulling one on someone whom you are trying to bring in (4.1/2). But I know from a commentary on a later episode of the show that some officers do bear arms now in their work and others don't. Not to mention that the world in Section D is certainly a much more dangerous place and involved in missions where firearms are more justifiably used than Tom's seasons.
