James is a very stoic yet outgoing character. He can enjoy a nice conversation with a crew mate while transforming into a calm and decisive officer as soon as the need arises. He takes his duties and service to Starfleet seriously but is not without his charms on and off duty. His background and stoic personality finds that he bottles up his emotions and does not find it easy to confide in people. Especially one's he has not known for that long.
