Lance is by the book; religiously by the book. He has no sense of humor, reveals no emotion and never gives an inch. He has caused problems with his Captains in the past by refusing to cut corners or reduce his estimates. Likewise, he alienates his team by demanding they adhere to his timescales and do things his way.
Lance lives to work and works to send money back to his community. He is resigned to the fact he will rarely, if ever, see his own family again, but he lives to support them. That is his role.
From an early age, he was indoctrinated by his community with regards to his obligations and how to fulfil them.
He is usually the most unpopular officer on the ships he serves but, he usually also has the best track record.
