Captain Thorson is a MCRN Intelligence Officer
He is a very tall, thin man. His face is narrow and tight, the skull beneath it pressing to get out.
After the Ganymede incident, Captain Thorson, despite the protests of her doctor, Trisha Pichon awakens Gunnery Sergeant Bobbie Draper to debrief her. He proceeds to ask her why she and her platoon fire on and destroy the UNN outpost. Bobbie then tells him about the monster and how it attacked the UN soldiers and her platoon, killing all but herself. She says to back herself up that there will be combat footage of it from her platoon and her own suit but Thorson replies that the blast from the impacts if the battle destroyed her platoon and her own suit's video log is static. Bobbie tells him that due to her armor being an older Mark III, it she's different firmware. Thorson then has her armor brought up and is reexamined by Petty Officer Electrician's Mate Singh who then realizes his error, but before he could bring up the footage Bobbie passes out again. Once she comes to, Captain Thorson who has viewed her combat footage apologizes for not believing her and thanks her for her professionalism. Later, he visits her and apologizes for his attitude towards her and thanks her for professionalism. Afterwards he introduces Bobbie to Captain Martens, a grief councilor.
On their way to Earth on the Harman Dae-Jung Thorson calls Bobbie to a meeting with two other civilians to more accurately create a timeline of the incident. It is during the meeting with the hell of Bobbie that it is discovered that the monster was actually the source of the jamming signal.
Once they arrive on Earth, Bobbie and Thorson attend a meeting with the delegations from Earth and Mar. Three hours in and only the agenda being discussed Bobbie looses her temper and asks why no one has spoken about the monster yet. Furious Throson sends her into the hall. When Marten arrives Thorson blames him for not being able to keep Bobbie under control and then tells them they are both on the next ship back to Mars to answer to a disiplinary council. When Martens ask her how she feels she goes for a walk. Later, he calls Bobbie in for a meeting. When she arrives he tells her that he overreacted to realized the extent of her trauma still not believing her story. He goes on to tell her that she will be staying with him on Earth to repair the damage she caused at the meeting between the Earth and Martian delegates. She then refuses and leaves his office.
