I had always thought that he calls her "Mom", because sometimes he does. Last night, I was rewatching "The Source" and I could have sworn he called her "Mama". Does anyone recall a time when Clark calls Martha anything other than "Mom"? (And I'm not referring to those times when he's dressed in blue tights.)
Just curious. Thanks.
Had to watch most of the episode but it was at the end when Clark was saying his goodbyes to Jonathan and Martha. In the script it was covered as "The Kent's ad-lib goodbye to Clark and Lois and drift away with the staff, leaving our heroes alone." Clark does call Martha "Mama". Since it was ad-lib with no specific lines to say it just might be the way Dean refers to his Mom so he used it there.
