underestimate her. And she often uses that to her advantage". On the influence that the apparent death of Steve Rogers has on Carter, Atwell explained that "he was the greatest person she ever knew—even before he took the serum and became Captain America. She knew his character and she saw a kindred spirit in him. So I think she's grieving the loss of him but she's also determined to make sure that his work wasn't in vain. That gives her a tremendous amount of determination to carry on despite the obstacles that she comes across." Gabriella Graves portrays a young Carter. James D'Arcy as Edwin Jarvis: Howard Stark's butler and ally to Carter, who will eventually be a tutor to Tony Stark and inspire his J.A.R.V.I.S. artificial intelligence. Atwell referred to Carter's relationship with Jarvis as the series' "comic relief", and said "she needs someone who is in contact with Howard to help kind of run this mission[, and] they have this very witty banter back and forth". Fazekas explained that some of the character's persona "has come from the comics and some of it we've developed ourselves. Some of it is influenced by James D'Arcy himself and his strengths."

He did not study Paul Bettany's performance as J.A.R.V.I.S. when approaching the character.

Murray compared the character to Indiana Jones, and stated that "he's working his way up to become the head of the SSR. His goal in life is to just be great at his job. So he has a large chip on his shoulder, which gives him an attitude." Murray also noted that, unlike his character on One Tree Hill, Thompson does not serve as the "moral compass", which meant that he would not be "confined to a box" and would instead be allowed to "really play things up and do what's unexpected". For the second season, Thompson is made chief of the East Coast SSR office. Enver Gjokaj as Daniel Sousa: A war veteran who is an agent with the SSR and experiences prejudice due to his injured leg. "He accepts his injury, he accepts his compromised status in society ... Peggy says, 'Forget this. I'm Peggy Carter. I'm going to do
