Virginia is right--you had Martha down perfectly here
...
I'm not surprised that Martha and Jonathan don't want to leave the farm...even though it's maybe not the smartest idea. It's their home--their past, and (hopefully) their future. Maybe they are looking at the big picture a bit differently than Clark? They've seen Lois and Clark interact first-hand. They know Clark's feelings for Lois--but as outsiders, they've been able to watch Lois around Clark...get a sense of her friendship towards their son, whether or not she is trustworthy. Martha especially, seemed to really take to Lois from the beginning--and from this story, she definitely can tell her son has fallen in love. They really don't seem too worried.
I (think) I trust Martha and Jonathan's gut instincts here...
Great job, Feli!
