Simon is a Cylon agent who poses as a doctor caring for Kara "Starbuck" Thrace after her capture in "The Farm."

Simon tries to casually persuade her into bearing children but is unsuccessful. When his diplomatic efforts fail, he surgically explores her ovaries without Thrace's permission, either partially removing an ovary or its eggs. On orders from a copy of Number Six, Simon arranges a time to surgically remove Thrace's ovaries.

Before Simon could sedate her again and remove her ovaries, Thrace's suspicion that he is a Cylon is confirmed. In conversation he uses her call sign, which she never mentioned in his presence. Thrace kills him and escapes from the Farm.

Another copy of Simon is seen just as Thrace exits the building, a more well-kept copy in a dark business suit who greets Thrace just as she reaches the outside of the compound. Before he can speak further, members of the Caprica Resistance immediately kill him as they storm the Farm to liberate Thrace.

At least one other copy is seen on Cylon-occupied Caprica. (Downloaded)

Simon was the first new Cylon agent model revealed since the Miniseries, and brought the total number of known models to 5. The later revelations of D'anna Biers and Cavil as Cylons brought the total to 7.

Note

• Whether Simon has completely or partially removed one or both ovaries or just their eggs from Kara Thrace is unclear. The sentence that Kara overhears Simon saying to Number Six is, "Pending lab test results on the sample ovaries, complete removal will proceed tomorrow. If lab tests are positive, then subject will be moved to processing facility for final disposition." However, humans only have two ovaries, so it seems implausible that he would take a "sample" one, so perhaps the line truly meant "ova" (egg cells). It is clear that he didn't completely remove all of Starbuck's reproductive cells, as Starbuck escaped before "complete removal" took place.
• It is possible that this particular model, like the Valerii model, is prone to sympathizing with humans. He expresses regret, which another Six model notices, when discussing the possibility of removing her ovaries. Based on the lone scar that Thrace acquired, at most a single ovary was removed, if at all.
• Actor Rick Worthy doesn't actually appear in "Downloaded" and is uncredited: briefly during the cafe scene, we see another bald black man from behind. It is clearly implied to be Simon, however he is not credited and RDM stated in the podcast that it was just an extra standing in for him.

Spoiler follows, highlight to read.
The sample ovaries obtained by Simon were likely used in a cylon breeding experiment, as in a season 3 preview commercial Leoben is shown holding a baby in a tent on New Caprica saying "Say hello to your mother Kara".
