There are many, but the biggest one of all is after Starman and Jenny make love. It started pretty Narmy ("I gave you a baby tonight"). But he explains that the baby will be everything they both want. It will know everything the Starman knows, and will be able to teach Humanity. Plus, biologically it will be a clone of her dead husband, Scott, but can be the child Jenny always wanted with Scott. It was the greatest gift he could give her, considering she thought she was infertile.
"You are at your very best when things are worst."
Scott's first few episodes as he begins to accept his father are pretty heartwarming in general.
