I'm not sure I've read any of these before; if I did, it was a long time ago. The pregnant Scully fic was great for the banter -- I felt it was really true to the characters.

I really enjoyed Tesla's story, too. I like pretty much anything Tesla writes.

"At Sea, At Anchor" was very good. I'm assuming it's recent - the author name is unfamiliar to me. Glad s/he and Tesla are on AO3 so I could leave kudos.
