Lionel. In season one, Glover traveled from New York to Vancouver every week while filming his scenes because he was already committed to stage appearances in New York at the time. When portraying the character's struggle with terminal liver disease, Glover was inspired by a friend's battle with cancer; he said his friend was a "cheerleader to people", who supported and boosted others when they were feeling bad. When Glover's friend learned he had cancer he fought hard to get over it, but when he learned that it was terminal he went to bed and stopped eating until he died about ten days later.

Season five explores the relationship between Martha and Lionel. Both Annette O'Toole and Al Gough said Lionel was slightly attracted to Martha, but that she would never act on that feeling.

Glover said he could not determine whether his character is good or bad, so when he is portraying him in season five he tried to present everything as if it was "good". Glover said he believes Lincoln Cole's (Ian Tracey) actions in "Mercy" made
