User blog:Garr9988/Past WH13 Agents Timeline

So, I compiled a list of all known WH13 agents pre-2000, compiled from various sources (known characters, stated names, inventory pages, and shelving cards). I've bolded agents known to have been active in more than one year. Gladys worked for, at a minimum, 20 years. She would have worked alongside I. Gustavsen, Buck Mendell, N. Raumm, and Bernie Arkweir.

Jack Secord worked for 10 years. He would have worked alongside Theo. Cotton, S. Brennan, Charlie Martin, Gus, Rebecca St. Clair, H.K. Tsu, and Merle Vennuto.

Hugo Miller and Vanessa Calder were agents together some time before Artie Nielsen was hired, at least according to the wiki (whether Vanessa retired or changed positions before Artie was hired is unsure because the three of them, or at least Artie and Hugo, worked together and Artie didn't know they were dating. Additionally, their part of the timeline is muddy because Wikipeida leads me to believe Artie was hired at LEAST in 1978; in "13.1", presumably in 2010, Artie states the computer lab has been shut down for 35 years, placing that event in 1975 (or 1974 if Season 2 is in 2009). Meaning that Artie either knew when it was shut down and seemed familiar with it despite not being present; he WAS an agent for '74/75; OR the computer lab was shut down before Hugo had his incident with the Zoetrope. Artie was good friends with Hugo and was familiar with his personality and antics, which makes me believe the third option.

Since we don't know when MacPherson was hired, we can't be sure whether he also worked with Hugo and/or Vanessa as well, unfortunately.

Unfortunately, it's a bit hard to determine when Claire's past events took place (which I had to look into for Artie's info) because the date was never specifically mentioned, and clues are a bit confusing. Claudia had her 21st birthday in Season 4, but was 19 in Season 1. In "Secret Services", the episode with the flashbacks explaining Claire's past, Claudia says she was 7 years old. If that episode takes place in 2013, then it took place in 1999. The wiki says Claudia was 22 in Season 5 and Claire was 30, so in that same flashback Claire would be 15. And because Claire and Joshua are never seen or mentioned together, we don't know for sure which one of them disappeared first (though I'm assuming Claire went first and Joshua followed).

Luckily, what mostly matters is that we know Artie was hired between '74 and '78.

Oh yeah, interesting bit of trivia: Artie shares his birthday with Saul Rubinek: July 2, 1948.
