The Scottish representative of Knox Oil and Gas, Oldsen works with Mac to secure the deal. Here is Peter Capaldi (of Dr. Who fame) in his first film role, portraying an extremely awkward young man. He runs like Woody from “Toy Story”, lol.
I suspect that Oldsen is a Head Type, considering his physical and social clumsiness. He has a genuine honesty, though, that makes him endearing. (Unlike Mac, he would not make a reliable negotiator.)
Even though both men dress in business suits, which doesn’t leave much room for odd pattern or style choices, Oldsen seems like a guy who has a few strange pieces in his closet at home. I’m going with a Six for him. He has a dogged loyalty to Mac and a persistent (but not stalker) interest in Marina. When Happer mistakes him for Mac, Oldsen doesn’t care. He just wants to do the job. This is a Trooper.
