I'm watching this episode again and thinking why oh why did Mr. Landon do this episode this way? I read all the bios out but forgot their take on it except that Mary and Adam couldn't really raise a baby, it didn't make sense, you need to see or have someone that sees to raise a baby especially back then. Killing Mrs. Garvey, even she didn't know in an interview, but I suppose helping to save the baby would seem better than leaving it there.
I love this show, but certain episodes did go over the top and this was one of them.
Albert did do a fine job showing guilt and grief and in some ways it was nice to see people really grieve, not in the stoic way, many were shown too in past episodes, but in a painful angry way, that many have to go through.
As someone said after watching it, "Can we see Christmas at Plum Creek" again and forget this.
